I think in many cases you're correct. My point wasn't about the performance of the AI algorithms themselves though. In my experience most of the problems where I want to use AI the algorithm itself performs adequately. Getting the interaction with the algorithm sensible for a non-technical user is hard. If AI becomes prevalent enough that UI/UX people start thinking about it, I suspect it will be much easier to solve that problem, which to me is the bigger business problem with AI.
