As you’ve likely seen, a strange and perhaps positive chain of events unfolded over the weekend in the world of AI and what we might call human extinction discourse. Dario Amodei, CEO and cofounder of Anthropic, posted an essay calling for a global slow-down in AI development to allow more time to prioritize safety and what the industry calls “alignment” and pledging that Anthropic would take a series of steps in that direction unilaterally. Somewhat surprisingly, OpenAI CEO Sam Altman and archvillain Elon Musk stepped forward and said they agreed and appeared to agree to join Anthropic in the proposed slowdown.

Regardless of what one thinks of AI and its possible dangers — existential or otherwise — it’s hard not to see this as at least a somewhat good development. And I say that with full cognizance of the various arguments about financial overextension or heading off sterner regulation that may make these moves self-interested. (AI critic Gary Marcus gives it a qualified endorsement along with a good cross-section of responses.) But I wanted to step back for a moment and talk more generally about the question of “externalities” which has always been the problem lurking in the background of Big Tech’s road to national and global domination.
