Send it to the tech giants investing billions of dollars developing quantum computing. I suspect they disagree with the conclusion.

quantum computers are a hype boondoggle. i don't think they are practical without 1000000x more power than LLM GPU rigs. they will do victory laps when they finally get one to crack one fucking pubkey after spending a million dollars worth of power running it, and we are all supposed to be terrified they will compromise bitcoin. lol. whatever.

Companies like IBM and (iirc) Google use quantum computers in labs purely as a marketing tool. Each year they proclaim a new success. “Now 4 qubits working!”. So the average watcher will extrapolate and think: “In 10 or 20 years” the fully working QC will become available. NOT considering the limits set by the laws of nature. Time travel will be available sooner than quantum computers. (I mean: both never).

2018 was long ago

The author of that 7 year old essay basically claimed that error correction is infeasible. But there has been significant progress in this area since then. Experimental error correction beyond the fault tolerance threshold: https://www.nature.com/articles/s41586-024-08449-y Here's one with 2^3000 parameters:

Continuous operation of a coherent 3,000-qubit system

doesn't change the fact it's just propaganda, and propaganda against elliptic curve cryptography. which they are doubling down on now since it's effectively securing bitcoin.
