I'm not so sure. The user experience has really crystallized over the years. It's not hard to imagine a smart tv or something like it just reimplementing that experience in hardware in the not too distant future (say 2055 if transistor and memory scaling stall in 2035).

We live in a special time when general processing efficiency has always been increasing. The future is full of domain specific hardware (enabling the continued use of COBOL code written for slower mainframes). Maybe this will be a half measure like cuda or your c++ will just be a thin wrapper around a makeYoutube() ASIC

Of course if there is a breakthrough in general purpose computing or a new killer app it will wipe out all those products which is why they don't just do it now
