You are raising good questions, though they are probably beyond the scope for me to answer.  My high-level take would be that there are quite a few existing laws that could apply in such a scenario (eg Neuralink-implants to record brain-activity need FDA approval) and that we should expect laws to be adapted to new circumstances caveated with the pacing problem.

That is a very fair point! I guess even within human laws there is some point before "God-level" where the "automation overhang" is reduced when AI becomes so good that it can compete with the product/services of many companies end-to-end rather than relying on integration into business processes. Still, I think it's fair to say that a) business integration can be/is a bottleneck to automation and b) "automation overhang" differs between products/service based on market structure (eg lower in management consulting, higher in public transport)
