If you look at the articles over the last few years you will see that no they haven't. The types of articles showing up here seem to have followed a pattern similar to other new technologies (curved screens, 3D TV, VR) where it starts off with articles discussing the technology from a technical perspective, moves on to discussions speculating on potential growth and impacts on the wider community, starts moving onto financials of the companies involved and then moves on to decline in interest.
This is normal human behaviour. How many times have you gotten a new device (car, phone etc) and been really interested in some new feature. You initially use it quite a bit and are excited about it but then the novelty wares off and you start to use the feature less. You don't necessarily stop using it but it doesn't turn out to be this "game changing" thing as initially thought.
I believe that AI is going through a similar trajectory and the articles on here are really just reflecting that.
It doesn't mean that AI is going to go completely bust, just that it has been overhyped and is now starting to fall back down to where it should naturally be. However people that have overinvested in the type are desperate to try and keep the hype going and will go all out in trying (which with hype, you have to really).
