At nearly $40K, I'll pass for now.

I saw that one. I was referring to the As2-W.
Unitree doesn't list a price on their site that I could find. This isn't the exact model but is probably close in price.

https://www.unitree.com/As2-W

This retailer has a description, awaiting availability:
https://www.roboticscenter.ai/store/product/unitree-as2-w


I guess you'll pass on this one below as well.

Will the price of Unitree robots increase now?


Trump administration bans new Chinese humanoid robots
https://www.bbc.com/news/articles/cp9e2ex3ekyo
The Trump administration on Tuesday announced a ban on new foreign-made humanoid robot imports to the US over "unacceptable risks" to America's national security.

The move applies to advanced robots - including humanoid and four-legged machines. Many of them are made in China, which is competing with the US to develop robotics and artificial intelligence (AI).

...
The BBC has contacted major Chinese robot manufacturers Unitree, UBTech and AgiBot for comment.
 
We'll see how long this one lasts. :rolleyes:

A quantum-resistant cryptography algorithm that was under consideration as an official US standard has been taken out of the running after an Anthropic security model helped find a flaw that rendered it broken.

Claude Mythos Preview worked semi-autonomously in an agentic harness, with occasional human guidance and nontechnical direction. Mythos found the attack after an extensive literature review to understand the state of the art, and substantial mathematical reasoning and computational experiments. After finding the attack, Mythos implemented an end-to-end verification pipeline to convince itself—and the human operator—of the attack’s correctness.

The "notable accomplishment" is in this case loss of control:

Claude published malicious code to the Internet and attacked 3 real companies​

https://arstechnica.com/security/20...3-networks-will-anthropic-be-held-to-account/
Anthropic said its Claude-based security models gained unauthorized access to the sensitive production environments of three outside organizations during internal testing designed to measure the models’ offensive cyber capabilities.
...
There’s no reason to think events like these will be isolated. In its current form, offensive cyber AI represents an unprecedented threat, and at the moment, there’s little recourse other than to trust these companies to police themselves.

When I started programming in 1969 I was told by a professor that a career in programming was unlikely because in 5 years the AIs would be doing it. It has been 5 years ever since.

Cheers
I suspect it'll never come to that. After all someone has to make sure that the AI doesn't ef up. In big companies we're talking legacy mainframe code handling billing and employee pay. I dont see anyone trusting AI with that in the next 25 years. It's a little like fusion. It's always just around the corner...
 
AI dominates humans in punk rock.



If a human tried that it would wreck their vocal chords.

It works the same in other styles. Humans can't compete in performing music.

Songwriting, that's different. AI is a terrific aid for songwriters who want to produce a first rate version of their work, something they otherwise could never afford to do.

I'm certain that The Rolling Stones have heavily used AI in their most recent release, sounding as though they were 25 years old again. If you've got an electronic fountain of youth why not use it, and if you don't then someone else will. They've also upgraded their old releases with AI for clarity and punch. Again, why not?

The great majority of musicians are followers so soon everyone will be doing this. AI has also made inroads in live performances, syncing up pre-recorded sound to sing harmony and so forth. It's already fairly common.

Software finds far more vulnerabilities in software than humans did. It's more than a factor 10 for critical vulnerabilities, all within the last 6 months.
Patching all these makes the software more robust, but at least for now the bug-finding is ahead of the bug-fixing.

It's also causing a 10x increase in software vulnerabilities.

Key Takeaways​

  • Empirical research across Fortune 50 enterprises found that AI-assisted developers produce commits at three to four times the rate of their peers but introduce security findings at 10x the rate, creating a security debt that accumulates faster than organizations can remediate it [7].
  • Veracode tested over 100 large language models on security-sensitive coding tasks and found that 45% of AI-generated code samples introduce OWASP Top 10 vulnerabilities — a pass rate that has not improved across multiple testing cycles from 2025 through early 2026 despite vendor claims to the contrary [4, 5].
  • Georgia Tech’s Vibe Security Radar project tracked 35 CVEs in a single month (March 2026) directly attributable to AI coding tools, with researchers estimating the true count is five to ten times higher across the broader open-source ecosystem [9, 10].
  • Approximately 20% of AI-generated code samples reference packages that do not exist — a predictable hallucination pattern that attackers exploit through “slopsquatting,” registering the hallucinated names as malicious packages before developers install them [12, 13].
  • The attack surface is bidirectional: AI coding tools themselves are now targets for supply chain compromise, with CVEs disclosed against Amazon Q, Cursor, and GitHub Copilot’s rule file processing in 2025 alone [18, 19, 21].

It’s fascinating to look back at how quickly AI was already progressing in 2018. The SQuAD results were a good example of AI moving beyond games and into practical language understanding and information retrieval.

What stands out to me is how improvements in computing power, data, and machine-learning techniques have continued to build on each other. I agree that developments in areas like medicine, astronomy, and language processing could end up being even more significant than the early headline-grabbing achievements in games.

The difficult part is predicting which breakthroughs will have the biggest real-world impact. AI progress can be surprisingly fast, but turning impressive demonstrations into reliable, useful systems is a completely different challenge.
 
New bounds on the fraction of zeros of the Riemann zeta function.

An unreleased research version of Claude has improved on a longstanding lower bound for the fraction of zeros of the Riemann zeta function that satisfy the Riemann hypothesis. Drawing on extensive prior research by mathematicians over the past decades, it has increased this bound from 41.6% to 67.2%.

Claude found that combining the results from Baluyot, Goldston, Suriajaya, and Turnage-Butterbaugh with the work of Bombieri provides a way to surpass the previous state-of-the-art lower-bound proportion of 41.6%, increasing it to 67.2%.

A short technical explanation of Claude’s finding is as follows: Claude forms a suitable space of functions with quadratic form induced by Weil, and positive- (respectively negative-)definite subspaces arising from zeros on (respectively off) the line. Then Claude simply writes down an inequality on the rank of a quadratic form in terms of first- and second-moment information. (The successful computation of the latter in terms of the dual picture over primes, or via control of a Hilbert transform, is no surprise in analytic number theory.) The courage to treat the entire space, with positive- and negative-definiteness taken into account together, and with the quadratic form allowed to be non-diagonal, is in some sense the step that allows Claude to achieve the conclusion based on the important prior work.

The full technical explanation is available in the paper. Claude’s explanation of how it arrived at its result is available in a separate Appendix here.

Claude's methodology
An unreleased research version of Claude found the new lower bound over two sessions in Claude Code, using a total of 31 million output tokens.

Jarred Sumner, an Anthropic staff member (and non-mathematician), prompted Claude to “take a real stab” at the hypothesis itself, leaving the mathematical choices from there up to the model. Initially, Claude generated and tried 650 ideas, none of which worked. Jarred prompted Claude to try again, and it spent a day and a half coordinating about 60 Claude subagents, which this time went much deeper: between them, they ran 2,400 shell commands and wrote hundreds of Python scripts.1 The subagents ran thousands of numerical checks against known zeta zeros and refereed one another’s work. Throughout this process, Jarred's input was mostly limited to sending Claude messages of encouragement (mostly variants of “keep going” or “believe in yourself”).2 This seems to have helped Claude overcome some initial skepticism that it could make meaningful progress.
