I'm starting to doubt not just the feasibility of quantum computers but their possibility.

Let me give you an analogy. Let's say you have a wooden stick. You can use a stick to store information. If you think of the stick as being one unit long, you can place a tick mark anywhere on the stick, representing a real number. Real numbers have infinite precision, so you can store an infinite amount of information on a wooden stick.

Of course, it's absurd for obvious reasons.

I suspect the same will happen with quantum computing. While theoretically quantum computers are supposed to provide an exponential speedup for certain algorithms, actually implementing hardware to do that might require something equally as absurd as my stick example. Instead of an exponential speedup we might end up with something comparable to classical computers due to these limitations.

A quantum computer doesn't find the accurate answer in your world.

It finds one of the infinite worlds where the answer it reports is correct and then resolves you into that variant.

Edit: read that in a sci fi book were a researcher is resolved into a world where Neanderthals coexisted with humans. Both the researcher and the Neanderthals in their own timeline he met were working with their quantum computer until their world's time lines mixed. Was pretty cool until the author said Neanderthals were homos. Damn homos have to inject their homo justification in every story now.

It really makes ya wonder how long they're going to keep denying the "hidden" explanations. It's not like they're hiding these days, outside of the retarded and distracted masses who wouldn't understand even if you did explain it to them.

It's getting so boring with all of this denial and fabrication. When do we get to the part where people start demanding answers? Hasn't this gone on long enough?

You don't necessarily need to do the original calculation to check it.
