Of course, but it’s also possible that the form of computing doesn’t exponentially scale either, fundamentally. It seems all the “apparent” scaling has also been just using traditional computing to imitate quantum to make it look like qubits are scaling exponentially like traditional computing.

It’s very possible, that like dozens of other styles of computing that have been tried, where we have found that the only one that scales exponentially was digital computing (von Neumann).

I think because we desperately want to apply the lens of digital computing onto quantum, since it’s the one that has become ubiquitous, we forget that there were dozens of other types of computing that were tried and all hit impassable walls. They could never make general purpose compute, and the best they ever achieved were extremely limited uses that digital computing quickly outpaced due to its simply capacity to scale exponentially.

And when all our major WC progress seems to be us attempting to attach it to tradition computing via “virtual qubits” but they still just can’t factor anything with more than 2 or 3 bits worth of genuine entropy, that sounds like a “we must have an apparent order of magnitude scaling to get our next round of funding, so make it happen” sort of situation to me.

In other words, there’s nothing wrong with preparing, the asymmetric cost of not having “insurance” on this issue is too great to not at least explore all options. But it absolutely is not an inevitability, and the world is FULL of bullshit and it needs to be looked at with an insanely skeptical eye. 10x that skepticism when the proposed solution demands that we **preemptively** freeze innocent peoples bitcoin to “save everyone” from it.

I understand it's very different and that it isn't likely to replace non-quantum computing in our lifetimes, if ever. It doesn't need to replace general computing to threaten public key crypto. It just needs to scale up in qubits and preferably remain stable. There's a lot of very smart people working only on this and with basically unlimited funding. What's commercially available is likely not even the bleeding edge, given the intelligence applications.

I'll agree that CRQC it's not absolutely inevitable. However, nobody can claim it's impossible either. It would be hard to even prove it doesn't already exist somewhere.

There's already relevant non-QC attacks against P2PKH. If they're not moving them to SegWit, they're already at risk. If a fork is propsed and they still don't move, that's on them. I would like to know how many coins/wallets are affected, if anyone can answer that.

Quantum computing's potential to break public key cryptography is a serious concern. The fact that non-QC attacks against P2PKH already exist and that SegWit adoption is crucial to mitigate some risks is important. Determining the extent of P2PKH vulnerability and tracking adoption rates is a worthwhile endeavor.

nice try, fed ai

All that indicates is that cryptography generally has a shelf life. But that’s always generally been the case. Doesn’t mean QC is what will put the current paradigm at risk or tha some quantum safe lattice signature is the solution. In fact, it could very likely be something totally different and that we don’t expect.

you can't prove your bullshit quantum resistant cryptography are safe either, animal

It's not my cryptography. You could do like Signal and layer existing algo and quantum resistant algo.

Is animal supposed to be an insult? We are all animals.

What non-QC attacks are you referring to?
