I am very very doubtful that people will once again start caring.
Even a decade ago, it was known that hardware gains wouldn't be as spectacular as before. It was predicted that this would lead to rise of specialized programming models such as GPGPU, DSPs, more focus on optimization, with a particular eye to hardware architecture, memory access patterns etc.
What actually happened?
Everything runs in the browser buried under six layers of Javascript and talks to a bazillion servers running microservices and passing JSON over HTTP to each other.
People care about optimization even less today than they did a decade ago.
