The fundamental risks are corporations and other organisations that use AI to extend the speed and reach of their aims.
If they are not being regulated for their current non-AI-amplified activities then we've already lost the race to control them as they get faster at doing undesirable things.
It's the same with disinformation. If we can't face up to powerful organisations (including governments, political parties, churches, ...) distorting the public sphere, then those very organisations are not going to allow regulation for AI that would have to limit their current practices.
