Time will tell. I think DL is amazing, but is no the right path towards solving problems such as autonomy. I think if you enter this field today, you should definitely take a look at other methods than DL. I actually spent a few years reading neuroscience. It was painful, and I certainly can't tell I learned how the brain works, but I'm pretty certain it has nothing to do with DL.
When I first start working in 2004 "data mining" was the big thing and it was going to solve all our problems. Nowadays I'm hearing the same thing again about "Machine Learning".
It's pretty natural to be skeptical people make big promises it ends up being a lot of hot air.
