As for my opinion, comparing QC to early silicon computers is very misleading, because early computers improved by becoming way smaller. QC is far closer to the minimum possible size already, so there won’t be a comparable

Thanks for saying this. I see a lot of people who assume all technology always gets better all the time. Truth is, things do have limits, and sometimes things hit a dead end and never get better than they are. Those things tend to get stuck in the lab and you never hear about them.
