These don't tend to utterly destroy an industry, but they are often successful in forever transforming it. Just ask Big Tobacco. No new laws needed: if your product hurts someone else, you're eventually going to be found liable, regardless of your arbitration clauses. Additional laws will just slow down innovation, which will itself cause harm (AI is already becoming quite good at recognizing melanomas, for example)
Lol, wtf. Tobacco delayed any punishment for decades before general public sentiment changed enough to go against them. In light of the AI race, we'll already have our heads blown off by a terminator before the legal system will present any significant delay for them.
If we're on a similar timeline with AI if we reach a consensus that AI is dangerous today, then we'd be looking at a big lawsuit finishing up around the year 2070, give or take a few years. I'm not sure if we need regulation, and I'm definitely not sure that regulation could actually be effective for this, but tort a la the big tobacco lawsuits is definitely not a reasonable alternative.
