> Google loves to kick senior execs upstairs.

The Japanese corporate culture has a name for this: Madogiwa-Zoku (窓際族) or “The tribe by the window”.

As what? CEO? Demis will not take up the MTS role.

The labs are all very interested in bio right now. Demis is working on Isomorphic rn (Google's version of that) but I could imagine a lab tempting him away to work on their equivalent if it had stronger momentum

He is probably itching to get to Anthropic. After all he is one of the early investors too.
