That one can probably be handled (temporarily) just by using a longer key. Which can give you time to do the switch.

The problem is that there's a lot of stuff already recorded that can't be protected that way.

That said, what quantum computers should really be good at is material design, quantum modelling, etc. But they need to be quite a bit stronger. (OTOH, DWave sells a specialized quantum computer that's reported to do a decent job in it's particular niche. It's just not a general computer. IIUC, it only handles relaxation problems.)

However, Florida is a small enough part of the global problem, that what they do locally will have essentially no effect. They couldn't fix the problem with local actions, and they also probably can't make it measurably worse.

Note that the US is not such a small part. That's a large enough fraction of the problem to make a measurable difference. Scale is significant.

I might well agree that the current administration is worse, and scale does, indeed, matter. But judging scale when one side is crippling state governments and the other side is removing individual rights isn't clear. The events are too different.

One can say that "morally the crippling of state governments to enfranchise the disenfranchised" is better, but it's still a centralization of control.

To be fair, both sides have uniformly supported measures to increase the government's control over the citizenry. They tend to support different measures, with different arguments, but both do it. This is basically because people act to make their jobs easier. The differences are because they have (sometimes only slightly) different goals, or "centers of power".

Note that this applies to the Warren Court and the civil rights decisions as well as to the current more blatant authoritarianism.

Comment Re:Python ? (Score 4, Informative) 75

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.
