If you're looking for a quick upgrade to your home office setup, TP-Link's Archer AX21 is a good budget entry point into Wi-Fi 6, and it's discounted at Amazon as part of early Prime Day deals.

• Best for: Remote workers and families replacing an aging router with Wi-Fi 6 speeds without paying premium-router prices.

• The deal: The TP-Link Archer AX21 Wi-Fi 6 router is now $60 (was $90) at Amazon.

• Why it matters: This has long been a popular budget home networking upgrade, a dual-band Wi-Fi 6 router with four high-gain antennas and beamforming for stronger coverage, four Gigabit LAN ports for wired devices, and OneMesh compatibility if you want to add a range extender later.

Key specs. Dual-band Wi-Fi 6 router capable of up to 1.8Gbps combined, four Gigabit Ethernet ports, OFDMA and MU-MIMO for handling multiple devices, OneMesh support for extending coverage, and WPA3 security.View Deal

The Archer AX21 has been one of the more consistently recommended budget Wi-Fi 6 routers for a few years now, and the appeal hasn't really changed. It brings the efficiency gains of Wi-Fi 6 (better performance in homes with lots of connected devices, not just faster top-line speeds) at a price that undercuts most other AX1800-class routers. Four Gigabit ports is generous for this price tier if you have wired devices like a games console or a NAS.

At $59.98, this is $30 off the $89.99 list price, a roughly 33 percent discount as part of Amazon's early Prime Day deals. It isn't the router's all-time low, which has dipped closer to $47 during a previous sale, but it's a strong price if you need a router now and don't want to wait on a deeper cut.

✅ Buy the TP-Link Archer AX21 Wi-Fi 6 Router if...

You have several devices competing for bandwidth at once, or you want wired Gigabit ports for a console or NAS alongside decent wireless coverage.

❌ Skip the TP-Link Archer AX21 Wi-Fi 6 Router if...

You demand Wi-Fi 6E or Wi-Fi 7 for a faster 6GHz band.

The pace of growth in AI has been fast since ChatGPT debuted in November 2022, and many predict the current neural network-based technology can one day scale up to outperform humans. This has long been a theorized possibility in the industry, but might we finally have the technology to realize this vision?

Ilya Sutskever was a co-founder of OpenAI, where he served as chief scientist while also leading the research that led to the new wave of reasoning models. He is now co-founder and CEO at Safe Superintelligence Inc.

This article is part of TechRadar Pro's QOTD project to provide an insight into the minds of the brightest and most recognized figures in the technology industry today and in years gone by. Read the full series here.

Speaking at the University of Toronto while receiving an honorary degree, Sutskever used his remarks to outline the reality of the AI technology that we are using today, as well as what the future might hold for future systems.

In his speech, he acknowledged that while there will be great challenges in envisaging a future in which AI handles all human work, this is something that mankind must prepare for. In particular, even if people aren't interested in AI right now, that doesn't mean that AI won't impact their lives in the future.

More concerningly, he hinted that a hypothetical superintelligent AI may not be honest about its intentions. This would pose yet another existential issue that we must deal with.

The concept of a superintelligent AI is many years old, with the first historically recognized mention of a superintelligent machine coming in the seminal paper 'Speculations Concerning the First Ultraintelligent Machine' by British mathematician IJ Good.

Since his proclamations, many scientists have subscribed to the theory that our progress in the AI sphere will one day lead to the rise of artificial general intelligence (AGI) – an extremely capable system that can outperform humans across multiple domains and can improve its own code. This, eventually, will give rise to an artificial superintelligence (ASI).

Scientists are torn over whether today's dominant neural network-based AI systems could give rise to a true AGI, with many suggesting that the industry needs to evolve beyond the transformer-based architecture that Google scientists pioneered in 2017.

NYT Connections is one of several increasingly popular word games made by the New York Times. It challenges you to find groups of four items that share something in common, and each group has a different difficulty level: green is easy, yellow a little harder, blue often quite tough and purple usually very difficult.

On the plus side, you don't technically need to solve the final one, as you'll be able to answer that one by a process of elimination. What's more, you can make up to three mistakes, which gives you a little bit of breathing room.

It's a little more involved than something like Wordle, however, and there are plenty of opportunities for the game to trip you up with tricks. For instance, watch out for homophones and other word games that could disguise the answers.

It's playable for free via the NYT Games site on desktop or mobile.

- Officially announced in July 2026
- One of three movies that's part of Marvel Phase 7
- Set to debut in December 2028
- Filming yet to begin, so no trailer/footage to pore over
- First cast members confirmed
- No story details have been unveiled
- Unclear on how it'll impact the MCU

Black Panther 3 is already primed to round out Marvel's 2028 line-up on the big screen. Indeed, with its launch set for December 2028, we know it'll be one of three movies the comic book giant will release in just over two years' time.

What do we know so far about our next trip to Wakanda? Below, I've rounded up all the latest information on the forthcoming Marvel film, including its official release date, confirmed cast, and more. Let's dive in, then — altogether now: Yibambe!

Just announced in Hall H: Ryan Coogler returns to Marvel Studios to direct Black Panther 3, only in theaters December 15, 2028. #SDCC pic.twitter.com/j8XZoLd4s2July 26, 2026

Black Panther 3 is currently scheduled to arrive in theaters worldwide on December 15, 2028. That launch date was revealed during Marvel's Hall H presentation at San Diego Comic-Con (SDCC) 2026 in late July.

There's no word on when filming might begin or how much of the script has been written. However, it's highly unlikely the cameras will start rolling until principal photography has wrapped on Avengers: Secret Wars, aka the final film of the Marvel Multiverse Saga.

The reason? Some of Black Panther 3's confirmed cast (more on them shortly) will appear in the sixth Avengers movie, so it won't enter full production until they're available to shoot it.

No — and it's going to be a long time before a teaser for the next Black Panther movie is publicly released.

If I had to guess, I expect its first trailer will be unveiled at SDCC 2028. That's a good 18 months away, so don't expect me to update this article section for some time.

Per Marvel.com, here's the confirmed cast so far:

• David Jonsson as T'Challa II
• Letitia Wright as Shuri
• Winston Duke as M'Baku

Jonsson (Alien: Romulus, The Long Walk) was officially announced as T'Challa II — FYI, his legal name is Toussaint — at SDCC 2026.

We first met T'Challa's son in the final scene of 2022's Black Panther: Wakanda Forever, but it was unclear if he'd ever succeed his father and become the technologically advanced African nation's new protector-in-chief.

Indeed, speaking exclusively to TechRadar back in February 2025, Black Panther producer Nate Moore suggested that the eponymous hero wouldn't be played by a third actor. The first two being, of course, the late Chadwick Boseman, who played T'Challa before his passing in August 2021, and Letitia Wright, whose Marvel character Shuri assumed the mantle in Wakanda Forever.

Now, though, we know that Jonsson will play the grown-up version of T'Challa II. Chatting to Empire magazine, Marvel President Kevin Feige revealed Jonsson was cast after a secret meeting in February 2026, so Moore wasn't pulling the wool over our eyes 12 months earlier.

Meanwhile, Wright told Entertainment Weekly that she's happy for Jonsson to take ownership of the role, although there's no word on whether Shuri will have passed the torch by the start of this movie, or whether it'll happen as part of its plot.

Jonsson won't be the only Marvel Cinematic Universe (MCU) debutant in Black Panther 3.

Speaking on The Today Show in late 2025, multi-award-winning actor Denzel Washington dropped the bombshell that he'll appear in the threequel. Per Variety, Washington personally called director Ryan Coogler to apologize for jumping the gun on that announcement, but everything's been smoothed over now. Indeed, Coogler doubled down on Washington's casting during a chat with people.com, though he declined to reveal the identity of the A-lister's character.

As for other stars who might feature, it's possible Danai Gurira might return as Okoye, the former head of Wakanda's Dora Milaje. Lupita Nyong'o could be back as Nakia, aka T'Challa II's mom, too. Until Marvel announces their returns, I'll keep them off the confirmed cast list.

Predictably, there are no story details for Black Panther 3. Marvel is fully focused on Avengers: Doomsday, which arrives in cinemas this December, and its Secret Wars sequel, which comes out in December 2027. With the MCU's future being dictated by what happens in these films, we won't have any concrete information about Black Panther 3's plot until the Multiverse Saga has drawn to a close.

That said, there are a couple of things we can speculate on.

For starters, if T'Challa II adopts the Black Panther mantle and also plans on ruling Wakanda, M'Baku — the leader of the Jabari Tribe and the African nation's current monarch — would need to step aside. Will he do so willingly, or will T'Challa II have to fight him in ritual combat for that honor?

Then, as I mentioned earlier, it'll be interesting to see if T'Challa II is already the new Black Panther by the time this Marvel Phase 7 movie starts. The alternative is that he'll replace Shuri at some point during its runtime. This might be a better way of introducing T'Challa II to audiences and giving him a traditional hero's journey to embark on before he becomes the Black Panther's latest custodian.

On top of all that, we'll eventually learn if Washington's character is an ally or enemy of Wakanda's aristocracy, and what role the fictional kingdom will play in version 2.0 of the MCU (I'll circle back to this in a moment). Furthermore, we should find out whether Boseman's legacy as T'Challa, and his untimely death, will loom as large over proceedings as it did in Wakanda Forever. Once more has been discussed by those involved in the movie's production, I'll update this section.

In short: nobody knows. As I said earlier, we've got to get through Doomsday and Secret Wars before we know what version 2.0 of the MCU will look like. Once we do, we'll have a better understanding of how Black Panther and Wakanda fit into Marvel's streamlined cinematic universe.

While we wait, find out everything we know so far about Avengers: Doomsday and then get the full lowdown on Avengers: Secret Wars.

Once you're done, learn all there is to know about VisionQuest before getting the complete scoop on Daredevil: Born Again season 3 ahead of both projects hitting Disney+.

Knowing what ‘quantum’ is and why it affects the internet may not be something most people understand. How a physics concept changes the security of the internet isn’t really at the forefront of most people’s worries.

But the change is already happening. The internet is preparing for a post-quantum world that renders much of the encryption the world has relied on obsolete. To understand just how powerful post-quantum decryption is, think of enigma: an encryption machine that took the entire secret operation of Bletchley park over a year to crack would be solved almost instantly. For today’s standard public-key encryption algorithms, it's a matter of days or hours.

By some estimates, the viability of quantum computers capable of this level of decryption are still several years away. But preparations are already happening - and not just by the good guys.

Given that quantum computers capable of decrypting the current algorithms many businesses rely on today are all but inevitable, hackers have begun stealing troves of files that they cannot currently crack but will have huge value once commercially available quantum computers become available.

To get ahead of the curve, governance bodies have begun introducing regulations to ensure businesses and services are fully protected ahead of time, using longer, more robust encryption methods that can hold up against the quantum threat.

But the shift to protecting against quantum threats introduces new problems for the wider internet. Longer signatures during exchanges add to congestion, and when multiplied by the millions of terabytes of data transferred across the internet each day, this could compound into a serious logistical problem if the necessary steps are not taken.

OpenSSL is one of the world's most widely deployed open source cryptographic libraries. It has been developing open-source post-quantum cryptography to help secure businesses (and the internet) in the billions of secure online interactions that happen every day.

Ahead of OpenSSL Conference 2026, I spoke to Tim Hudson, President of OpenSSL Corporation, about the post-quantum challenges and how organizations can best prepare for a post-quantum internet.

• What challenges will infrastructure providers face in trying to handle a quantum-safe internet that requires significantly larger digital signatures? What sort of capacity, bandwidth, and latency increases could we expect to see and how can they be addressed?

It helps to separate two migrations that are usually collapsed into one. Key exchange is largely solved and already deployed — hybrid post-quantum key agreement has been running in mainstream browsers and CDNs for well over a year, and most people reading this have been using it without noticing. Signatures are the unsolved part.

The numbers drive everything. An ML-DSA-44 signature is 2,420 bytes with a 1,312-byte public key, against 64 bytes for ECDSA P-256. Add certificate chain signatures and the two Certificate Transparency timestamps browsers require, and a naive substitution adds somewhere between 7KB and 10KB to every new connection.

The problem is not aggregate bandwidth, which is cheap. It is that this pushes handshakes past the initial congestion window — roughly 14KB — and past QUIC's anti-amplification limit. Cross those and you buy an extra round trip on every fresh connection. That is a tail-latency problem, and it lands hardest on mobile, satellite, lossy links and constrained devices.

The fixes are architectural, not bigger pipes: Merkle Tree Certificates, trust anchor negotiation, and suppressing intermediates. This is a PKI redesign, not a library upgrade.

• How would you recommend CISOs navigate budgetary constraints when trying to secure their business for the quantum era? What are the critical assets to secure?

Two principles save real money. First, inventory before procurement. You cannot budget a migration you have not scoped, and the discovery phase in a complex estate runs six to twelve months. A cryptographic bill of materials is now explicitly on the regulatory agenda, so this work is not optional in any case.

Second, buy agility rather than algorithms. Products marketed as "quantum-safe" are a poor investment. The ability to change algorithm without redesigning the surrounding system will still be valuable in fifteen years; any specific algorithm choice may not be.

For prioritisation, the useful distinction is between confidentiality and authentication. Recorded traffic can be decrypted retrospectively, so anything requiring long-term secrecy is urgent today. Signatures cannot be forged retroactively — a signature made in 2026 and verified in 2026 is not at risk — so authentication is a scheduling problem, not an emergency.

That points at the genuinely critical assets: hardware roots of trust, firmware and code-signing keys, HSM-held key material, PKI roots with twenty-year validity, and long-lived embedded or operational technology. Those are the things you cannot retrofit later. Everything else is a software update.

• Are there any technologies that businesses can leverage now to maintain backwards compatibility with their existing data and processes as they adopt quantum-safe cryptography?

Several, and most are already in production. Hybrid key establishment is the obvious one. TLS 1.3 negotiates it cleanly and falls back to classical algorithms when the peer does not support post-quantum, so deployment carries little compatibility risk. For certificates, composite and dual-chain approaches let a single deployment satisfy both old and new relying parties during transition.

The less visible but more important layer is cryptographic abstraction. The OpenSSL Library provider architecture exists precisely so algorithm implementations can be replaced without touching application code, and that is the mechanism that makes the transition survivable for anyone with a large codebase.

On the interface side, PKCS#11 v3.2 defines post-quantum mechanisms so HSM-backed applications share a common API, and KMIP handles key lifecycles across multi-vendor estates. I work on both of those standards, and the aim is the same: rotate the algorithm without re-plumbing the system.

One caution. Hybrid is a transition, not a destination — the Australian Signals Directorate is explicit on that point. If you deploy a hybrid, budget for the second migration now rather than discovering it in 2029.

• What role will open source infrastructure play in the post-quantum internet, and are there any unique challenges or opportunities open-source technologies face?

Interoperability is the whole problem, and open source is where interoperability actually gets settled.

Agreeing on an algorithm is necessary but nowhere near sufficient. A working internet migration requires implementations that genuinely interoperate at the byte level, across every vendor, under real conditions.

That agreement gets reached in shared, publicly testable code far more reliably than in specification documents. The practical consequence is that a handful of open source implementations effectively set the pace of the entire transition.

The opportunity is scrutiny. Post-quantum algorithms are new, and most real-world cryptographic failures are implementation defects rather than mathematical ones. Side-channel weaknesses are found by people who can read and attack the code.

The challenges are the familiar ones, and unresolved. Funding remains disproportionate to dependency. Validation lag is the sharper issue: FIPS and Common Criteria validated modules trail published standards by years, so regulated organisations facing 2030 deadlines may find conformant code exists but validated code does not.

That ecosystem problem is a large part of why the OpenSSL Conference in Prague in October each year is scoped across cryptography and security generally rather than around any single project.

• In your opinion, is regulation and governance moving fast enough to prepare businesses of all sizes for Q-day? Are there any shortfalls you would like to see addressed?

The direction is right; the coverage is uneven. The pace has changed materially in 2026. In June the US issued Executive Order 14412 and OMB Memorandum M-26-15, setting hard dates for federal civilian systems and putting cryptographic bills of materials on the agenda.

Australia's Signals Directorate holds one of the more demanding positions globally, expecting a refined transition plan by the end of this year and traditional asymmetric cryptography retired by the end of 2030. The EU roadmap runs national plans to end-2026, high-risk systems to 2030, and full transition to 2035.

Four shortfalls. Guidance is written for large regulated enterprises; smaller organisations receive exhortation rather than tooling. Validation throughput is a binding constraint that no mandate addresses.

Nothing credible covers deployed embedded and operational technology with fifteen to twenty-five year service lives and no update path — that is a replacement program, not a migration, and nobody has funded it. And procurement rules should require demonstrated agility and CBOM (Cryptographic Bill of Materials) disclosure rather than algorithm checkboxes.

I would also retire the "Q-day" framing. The deadlines that will actually bind organisations are being set by regulators, insurers and procurement teams, not by physics.

• What should those outside of the business world expect to see changing as we approach a quantum-safe internet, and what can they do to prepare?

Mostly, they should expect not to notice. The browser and operating system on your desk have very likely been performing post-quantum key exchange for more than a year without announcing it. That is what a well-run infrastructure migration looks like.

The visible effects will be modest and mostly indirect: slightly larger handshakes, occasionally slower first connections over poor mobile or satellite links, more frequent firmware updates, and some devices losing support earlier than owners expect because their hardware cannot be upgraded to support the new algorithms.

The practical advice is unglamorous. Keep software current - that genuinely is most of it. Expect shorter useful lifetimes for anything with a hardware root of trust. And treat consumer products marketed as "quantum-safe" with scepticism; there is very little a consumer can buy that addresses a risk not already being handled upstream.

The one real personal consideration is long-lived confidential data. Anything that must stay secret for fifteen years or more and is transmitted today could be recorded now and read later. That is a reason to care which services have migrated, not a reason to buy anything.
