If you look back at the sci-fi movies that came out soon after lasers were invented, you could see that people had all sorts of crazy ideas of what a laser could be used to do and that a lot of them had absolutely no idea of what a laser really did. Ultimately, we've found out that most of those imagined uses were pure bullshit or extremely impractical, at least with the current state of the technology. It didn't mean that the technology was useless. We ended up finding all sorts of useful purposes for it that they had never imagined, like disk players or barcode scanners. It only means that it took time for people to better understand what the real world applications of the new technology was and a lot of the initial assumptions were dead wrong.

AI is going through the same process. It will take time before the technology's strengths and weaknesses are better understood by the masses so it can be better applied to more realistic uses. And for the commercialization of snake-oil applications for it remains confined to fringe markets.
