Yeah they'll probably have to invent new measures of computing power. I'm not sure that conventional computers will die out immediately though, it'll probably take time to transition
I think if no quantum computers are ever made to replace what we have, computing as we know it will either stagnate or have to scale back upwards in size.
Computing has already stagnated considerably because of planned obsolescence, incremental upgrades and monopolies. I'm definitely not saying that quantum won't become mainstream though
I just think the cost is going to be extremely prohibitive for the average user at first. Probably at least like 10-15 years before they're affordable for home computing at this rate
Probably much longer imo. We still can't run "hot" quantum. The only QC that we currently have that sort of work require near absolute zero operating temperatures and fall apart easily
The qbits even under these conditions destabilize too easily to perform any major real computing.
