Perhaps because professional investors would look more carefully at the numbers? Wouldn’t want that!

Anthropic Mythos announcement critique: Sandboxing disabled limitations
By
–
Yesterday’s Mythos announcement from Anthropic was overblown. • Sandboxing was turned off, so test didn’t show much about the real world. • Cheap open-weight models can (already) do some similar stuff • No evidence that Mythos itself is a major qualitative jump. In short,

Cybersecurity Warning: AI Mythos Reality Check
By

My considered opinion is that The Mythos stuff was mostly a myth. Take it as a serious warning sign that we need to get our act together with respect to cybersecurity. But don’t take the details seriously.

Folks, you can relax. Mythos is not some off-trend exponential gain. And the gains weren’t about recursive self-improvement. Good thread from @ramez

Tech Giants AGI Control Poses Existential Risk Society

This is literally why I wrote Taming Silicon Valley. https://t.co/ihTPmtbU8M
— Gary Marcus (@GaryMarcus) 8 avril 2026This is literally why I wrote Taming Silicon Valley. Big Brain AI (@realBigBrainAI) Director James Cameron on why Big Tech owning AGI is scarier than any science fiction he's ever made: "AGI will not emerge from a government funded program. It will emerge from one of the tech giants currently funding this multi-billion dollar research." And when that happens, he warns, you won't get a vote on it: "So then you'll be living in a world that you didn't agree to, didn't vote for, that you are co-inhabiting with a super intelligent alien species that answers to the goals and rules of a corporation." A corporation that already knows everything about you: "An entity which has access to the comms, beliefs, everything you ever said, and the whereabouts of every person in the country via your personal data." From there, the slide toward something far darker is shorter than most people think: "Surveillance capitalism can toggle pretty quickly into digital totalitarianism." And even the best-case outcome isn't reassuring. Tech giants becoming the self-appointed arbiters of human good is, as he puts it, the fox guarding the hen house. He's not buying the idea that these companies would stay benevolent with that kind of power: "They would never ever think of using that power against us and strip mining us for our last drop of cash." The sarcasm is the point. Cameron has spent four decades imagining worst-case futures on screen. His verdict on this one: "That's a scarier scenario than what I presented in the Terminator 40 years ago, if for no other reason than it's no longer science fiction." — https://nitter.net/realBigBrainAI/status/2041901452474642630#m

Neurosymbolic AI Vindication: Beyond Pure Language Models
By

it’s surely NOT a pure LLM (eg heavily uses symbolic tools and is hardcoded to do so), and surely includes neurosymbolic components, so it is to some degree vindication for my central claims.

Mythos ASI Claims: Competitive Advantage and Regulatory Reality
By
–
this is wrong for many reasons
– mythos is not ASI, not even ANthropic is claiming that
– others seem to be close behind, as I posted earlier today; it’s likely a 3 month “win” or something like that, not an enduring advantage.
– regulations and treaties are routine for many -
