Celestial Navigation is also doable even in daylight nowadays, e.g. https://sodern.com/en/ranges/astradia

Because you'd need to trash the old GPUs in order to make room for new GPUs. Right now new GPUs get online mostly in new DCs. TSMC fab capacity is much more limiting than DC building and it will likely keep being the case. It's much easier to build a DC than a fab.

Europe has passenger trains that work. What would be a short flight in the US, e.g. London to Paris is done more my train through the chunnel than flying unless you got a connecting flight.

It's quite possible other carriers would have gone around the worst and that the economy airline saved fuel.

Step 2, put the needle on a gantry (I suspect you'd need more like 5D CNC to enter the pore with the right angle) and seek and destroy hairs... As it is it saves money but not time nor skill...

That's one of the reasons I can walk in the main office of my registrar within an hour. It's clearly not available to everyone but it's especially important that if you can't do that you can at least conveniently sue your registrar... So at the very least in your jurisdiction.

So much is tied to DNS and particularly email...

The miners are the middlemen, and they can chose to take your transaction or not. Should bitcoin ever be actually used for payment, it's not to too far fetched to think miners could be forbidden to validate transactions involving a blacklist of addresses...

Actually, Ingas the company very much survived and moved to the Odesa region (https://ingas.ua/en/pro-nas/).

And they still have Neon in their catalog so most likely another case of impressive Ukrainian resilience.

Odesa is not and has been hit less than more Eastern cities. OTOH I'd assume Ingas in Mariupol ceased to exist for practical purposes.

The general point is not. Iceland and Easter Island were fully deforested way before the industrial age. Countless species went extinct in Britain and more examples abound.

"This is one of the few domains where having access to a quantum computer ahead of others could translate directly into financial gain"

Doubt, the moment people get vocal about their fund being stolen that will be it for crypto, it will crash the bank run. The only way it could work is that if you steal too little to be noticed, which will also be too little to finance your venture...

I'm working on just that in some IoT context, and a lots of chips I have to deal with only have hardware support for AES-128, so it's a little more complicated...

Yeah and some of the figures often quoted like consuming 14% of the electricity produced in the US are wrong, it was below 1%. https://ui.adsabs.harvard.edu/abs/2011APS..APRH13004R/abstra...

Yeah that's treating D-Wave "breaking" RSA-2048 as the fraud that it is. They didn't factor anything, they computed a square root.

I'm still dubious about the accelerated timeline given what quite a bit of what is presented as progress in the field is fraud or borderline fraud when inspected closely. (e.g. some of the recent majorana claims by Microsoft are at best overhyped, at worst fraud)

Sorry, the manufacturing learning curve. The most widgets you make, the cheapest they get. The effect was absolutely stunning for batteries and solar panels (https://ourworldindata.org/grapher/price-of-lithium-ion-batt...).

We make too few nuclear power plants for them to have a noticeable learning curve, and recently each subsequent one ends up more expensive than the latest, notably because of safety regulation. Korea and I think China had the best success in that regard (and France in the 80s) by being able to make real series, but you don't really see those now except maybe China.

It's one more instruction only if you don't fuse those instructions in the decoder stage, but as the pattern is the one expected to be generated by compilers, implementations that care about performance are expected to fuse them.

Not cost competitive with solar+batteries in many locales (less so the closer to the poles), and no learning curve, if anything a negative learning curve, nuclear never was more expensive than new nuclear.

And off course societal (and geopolitical) acceptance issues.
