Not sure how AR, AI/ML or even No Mans Sky belong to the same list as NFTs. No Mans Sky has delivered on many things over time and chances are you used AI for something today even if you aren't aware of it. Maybe you mean AGI and how near in the future some promised it to be. AR is too early to even judge, with only Microsoft investing into it out of the reputable companies AFAIK.
I do think there's a spectrum of pathological hype. On the one hand, there is manufactured hype, the NFTs and Theranos-end of the spectrum; on the other hand, there is hype from mismanaged expectations, the NMS side of the spectrum.
While NMS did eventually get their act together, what they delivered on launch was very much not aligned with the expectations.
AI solutions are hyped because they are AI solutions, not because of what they actually deliver. It's not that it has no uses, but the promises do not match up with the reality. Often it's enough to solve an already previously solved problem with AI to generate hype around a product, even if the AI solution is strictly worse than what's already on the market.
