Amodei, Altman, Hassabis, and Musk have spoken (albeit somewhat inconsistently) about the need to slow down to avoid AI existential risk.
Zuckerberg, Huang, and almost every VC say it's bullshit.
The difference is not that the first group is conflicted but the second isn't. They both are super conflicted.
If AI existential risk was to hype up the technology, why would Zuckerberg, Huang, and VCs be dismissing it? If it were "regulatory capture," why would Hassabis and Musk, neither of whom are at the frontier (sorry), be discussing it?
The difference is that the first group has been thinking about these risks seriously (at least off-and-on) for over a decade, since well before they ran large AI companies. The second has very clearly only engaged superficially, and is now annoyed that the first group's actions could dampen the massive profits of the AI boom for risks that sound like science fiction to them.
The terrifying reality is that these concerns are not being made up to sell a product or a policy. They have been around in some form since Turing, and fleshed out in great detail before OpenAI or Anthropic were a twinkle in their CEOs' eyes. They are fundamental to a technology whose entire purpose is to surpass human capacity, unless you are able to solve the very, very difficult problem of aligning the interests/goals of a more powerful agent with something as complex as human flourishing -- which the companies are very visibly failing to do.
They need to simply not build superintelligence, using anything remotely like current techniques, based on anything remotely like the present understanding of AI.
