Agreed. The hype surrounding machine learning is quite disproportionate to what's actually going on. But it's always been that way with machine learning -- maybe because it captures the public's imagination like few other fields do.

And there are definitely researchers, top ones no less, who play along with the hype. Very likely to secure more funding, and more attention for themselves and the field. Which has turned out to be quite an effective strategy, if you think about it.

The other upside of this hype is that it ends up attracting a lot of really smart people to work on this field, because of the money involved. So each hype cycle leads to greater progress. The crash afterwards might slow things down a bit, particularly in the private sector. But the quantum of government funding available changes much more slowly, and could well last until the next hype cycle starts.
