Most travel agents need a license, taxi drivers etc. Not sure why the same shouldn't apply for "AI"?
This post and another on this thread saying people will have to get a license for compilers or to hook compiler output to the internet would result in the very rapid disintegration of Silicon Valley. Surely there would be a head-spinning pivot against regulation if it looks like it will be that draconian. Otherwise a lot more innovation other than AI would be crushed.
