In rebuttal, Peter Gutmann seems to think the progress towards quantum computing devices which can break commonly used public key crypto systems is not moving especially quickly: https://eprint.iacr.org/2025/1237

That's not a rebuttal. The post references the paper and a rebuttal to it from an expert in the field.
>and a rebuttal to it from an expert in the field.
while i agree with filippo, the way you worded this makes me think that you may not be aware that gutmann is also an expert in the field. so, if you are giving filippo weight because he is an expert, it is worth giving some amount to gutmann as well.
I apologize if I flippantly dismissed the fact that experts disagree. That was not my intention. I was trying to point out that OP does address the referenced counter-point post specifically.

Damn. It's like I insulted Vault.
Also, I went over Filippo's post again and still can't see where it references the Gutmann / Neuhaus paper. Are we talking about the same post?
From Filippo's post: "Sure, papers about an abacus and a dog are funny and can make you look smart and contrarian on forums."

From the abstract:
> This paper presents implementations that match and, where possible, exceed current quantum factorisation records using a VIC-20 8-bit home computer from 1981, an abacus, and a dog.
From the link:
> Sure, papers about an abacus and a dog are funny and can make you look smart and contrarian on forums. But that’s not the job, and those arguments betray a lack of expertise[1]. As Scott Aaronson said[2]:
