This is one of those questions like what will you do if there's a solar flare that destroys the Internet? Should we really worry about this?
No, it is a waste of time when there are more pressing issues to be worked on. Fact is, most engineers and developers agree with my view that it is a waste of time right now otherwise they would redirect their time towards this. However, it is a good opportunity for spammers to write some useless shitposts and altcoiners in yet another quantum computing thread.
