Virtual reality in 1987, 1992, 1998?, 2005, 2015 ...

"parallel computing" has been the next big thing several times since Cray; but it never "died out", it just keeps grinding on the fact that human thoughts are pretty serial, and our computers mostly encode and track with our thinking.

Parallel computing's actually progressed pretty far. Virtually all GPU-based applications (unfortunatly, cyptocurrency mining being the most notable) are massively / embarassingly parallel.

As far as practical applications --- the set is vastly smaller, especially where there's a human in the REPL loop.
