Technically, it is similar to what happened with computers today — computers of old where warehouse sizes, in tightly controlled environments. The term debugging was a physical process of actually removing bugs from a computer. Lol. As computers became more affordable/smaller, they showed up in more places and allowed more people to use them. It appears the quantum computers of today are following the traditional evolution of computers. 40 years ago, people were able to rent time from university/business computers similar to what AWS Braket is offering. The reason question for me is what is the "PC" of the quantum realm. What will a quantum computer look like 40 years from now? I can't even imagine what it would look like, or what programing a quantum machine will even look like for the masses(AKA the python/ruby/java/c++, etc).

It won't hit PC levels until either cryogenics are commodity sized and priced for the home market, or room-temperature superconductors arrive and prove themselves still able to exhibit the Weird Quantum Effects that cold ones have. Look up "Josephson junctions", they're basically the transistors of QC.

My ideas are very fuzzy, but when people say that you can't run quantum computations at high temperature because of noise, it reminds me of something I read not too long ago about how scientists are starting to have insight into how biological systems operate in the presence of large amounts of noise from heat. So I wonder if there's a trick to it that nature already has found.

I'm no scientist but I would be very surprised if the brain is not harnessing similar effects or processes somehow. Consider microtubules, for example.
