It's good to be on watch for the bullshit (the news stories about Facebook's chatbots' "language", most futurist's predictions, any hype about general artificial intelligence, replacing x% of jobs in y years), but don't throw the baby out with the bathwater.
IMO, unlike blockchain, AI/ML is undoubtedly here to stay, and it will have a huge effect on everything.
I don't think it's a bad thing to try and apply new solutions to old problems but it just feels that we're trying to apply it too much to problems that are otherwise already solved.
That doesn't mean defense contractors, for instance, won't keep winning contracts based on that PR/marketing, while causing who knows how many innocent lives to be taken because of them over-stating the effectiveness of their AI.
That's just one example where AI is already "real" today, in the sense that many companies and government organizations have started deploying it and causing real harm to people because they think it's much better than it really is.
Other examples include anything from the AI being used in the justice system to AI "simply" being used to censor "porn" but censoring completely unrelated things in the process.
