It's very much the new blockchain. For the next year or so everything will have "AI" in the description because it produces a pavlovian response in VCs, then it'll move onto something else. So goes the tech industry.
None of this is new; there's a special magic phrase to attract VCs that changes every few years, and for now AI is it (we've actually been here before; there was a year or so a while back when everything was an "intelligent agent"/chatbot).
