PS: Just to clarify, I also haven't (yet) looked into what "AIs" can be used for today, or in the foreseeable future. And I've not had much time to keep up with the trade press lately. There's certainly quite a few things where it could plausibly be (or become) useful, aiui. Oh, and it seems to have replaced the crazy hype about blockchains (much harder to find plausible beneficial uses for that one - though the technology itself is genius), so that's something at least ;)

Also, technologies have a way of being used in unforeseen ways - Nobel tried to improve mining, and vastly increased our ability to kill and destroy. Facebook was, if a certain eMail is legit, developed to harvest personal data, and now it's used for everything from finding romance to creating the conditions for genocide - and for trying to stop genocide. So I wouldn't dismiss "AI" just yet, inspite of all its flaws and dangers (not the Skynet BS, more the "overloading participation" and marketing I mentioned earlier, plus the immense resource usage).
