I don't know what hype bubbles you're watching pop but the hype is at Cleganebowl levels in robotics, vision and autonomous vehicles from where I'm standing.
I mean, the first time we came to the thought of, "So we make this chain of weighted convolutions or whatever and end up with a system we can only kind of probe from on the outside and if we spend enough $$$ on data input it might get some good results" was back in, I don't know, 2014. Deep learning has gotten steadily better since, but I think it's getting more and more hype even if people are coming to that same realization.
