Same thing was said about Character AI, Cohere, etc. Companies started by the authors of the "Attention is all you need" paper. Look how that went... the team gets thrown around a lot as if it's the magic bullet. There is no magic bullet.

The ex-OpenAI people who started Anthropic are doing pretty great right now.

VC is a hits business. Just one hit pays for 9 that didn't work out.

Anthropic's Series A was $124 million; Typesafe's is 7x that. If Jev becomes a $2bn company it will be a failure to investors.

Anthropic raised their Series A a year and a half before ChatGPT had been released, when LLMs were still unproven technology and most VCs weren't paying attention to the field (they were mostly still chasing crypto).
