I think AI is a threat, but I don't see a "pause" as a practical solution.

I think perhaps a more practical solution is open-sourcing a safe-room protocol. And perhaps publicly subsidizing compute for it, so long as certain safety standards are met (e.g. free compute within our cloud environment so long as you're not feeding that output into a command-line etc). Maybe not the best solution, but certainly a better idea than nothing/hope-everyone-pauses.
