I like the term "hallucination", because with AI it now describes something made up because of a lack of understanding.

every single performance metric has been improving exponentially for most of the last two decades

Now you are hallucinating. The exact opposite is true. All scaling in QCs has been sub-linear and very likely inverse (!) exponential. Incidentally, factoring 21 is the current, actual, not-outdated-at-all record for a real quantum calculation.

If you want, I can also call you "delusional" instead of "hallucinating". Would fit about as well with what you just claimed.

I agree. The thing is that nuclear cannot be safe and economically viable at the same time. The only question is how different countries chose to make this impossible trade-off. The only rational version is, clearly, not to play this stupid game at all, but irrationality, greed and delusions are strong forces.

I also like the morons that claim nuclear is always available. These idiots do not even know the basics of a power-grid. For example, nuclear is not suitable as regulation energy at all and a grid with more nuclear than 70% cannot be made stable. The rest needs to be fast regulation energy because when a nuke SCRAMs, it begins to draw quite a bit of power for a long time and does so with no warning. Nuclear is about the most stupid, most limited, most unreliable and most expensive form of generating electricity.

What you don't understand is the Python is often used as a method of invoking libraries that are written in more efficient languages. And for the layer that it handles it doesn't introduce unacceptable inefficiencies. E.g., you wouldn't want to do ray tracing in Python, but it's fine for calling a library that does that.

I'm quite sure quantum computers are valid. Whether they're useful is another question. I'll agree that it's not clear that general purpose quantum computers will ever be useful. (I won't agree that it's clear they never will be useful.)

OTOH, specialized quantum computers are already useful. DWave sells one design.

At this time, this is the only rational stance left. There is no indication that QCs can ever scale to useful size, but a ton of indicators that they likely will not. There is not even solid proof that QCs work at all, because the longest, most complex complex calculation ever done successfully is apparently factoring 29 with a specialized algorithm for 29. That is easily in range for a conventional analog computation by non-quantum mechanisms. Hence while I think it is unlikely, the computation mechanisms that QCs rely on may still turn out to be hallucinations. Also note that even very, very, very minor deviations from the theory (and we _always_ had those in the past as soon as we had equipment to verify theory against reality precisely enough) would completely kill the QC idea. The precision required to do, say, a 128 bit calculation precisely, is unimaginable and a digital computer only reaches it by extreme measures.
