Non-US person here too.
From what I understand the majority of Americans want a single-payer healthcare system, but too many people in government are paid by insurance companies and affiliates to not change how things work.
What is it with code on blog posts where fonts have uneven size and/or font types (e.g. italics mixed in with regular)? I see this from time to time and I wonder if it’s intentional.
Think twice. Everyone who hosts the blockchain would decide to stop because he invested in crypto, at least with some hardware costs. Beside of the small group of people that owns a quantum computer. I don't expect that this group is >50% of the people that hosts the blockchain.
You don't need >50% of bad actors to compromise the blockchain, but rather >50% of the total hashing power. This could very well be achievable by a small group of people with QC at some point.
Clients need to be updated, too, since what's happening is that the server and client need to agree on a common algorithm they both support, but that's been in progress for years and support is now pretty widespread in the current versions of most clients.
Stragglers are a problem, of course, but that's why I thought this would be a harder problem for Bitcoin: for me to use PQC for HTTPS, only my browser and the server need to support it and past connections don't matter, whereas for a blockchain you need to upgrade the entire network to support it for new transactions _and_ have some kind of data migration for all of the existing data. I don't think that's insurmountable – Bitcoin is rather famously not as decentralized as the marketing would have you believe — but it seems like a harder level of coordination.
15 years ago a friend of mine was doing his PhD in laser physics and he was using diamonds to make a component cool faster. So the idea may be new in the chips space, but not new in general.
