I do not think a ban would be efficient. It would just force those who use AI to dissimulate it. I see it a bit as drug use, banning hasn't solved the problem ; and the countries who handled it the best were those regulating the use.

So I think we should look for a good regulation. It is more complicated to set up, but it has a chance to work.

In my mind, it should allow some projects to identify as not using any AI, and request that each project define what is their use of AI. Ideally, we could know this without opening the project (maybe thanks to a badge).

Also, shaming the use of AI only has the same aim as banning it: forcing it to grow hiden and out of control.
