It actually states, “This destroyes the RSA cryptosystem.”
Seems a bit like the way an old pirate might speak, or at least someone hundreds of years old.
Its a meme. "This kills the crab."
?
This is discussed here, at Hacker News. It's also discussed at many other places on the internet. :-)
Why is this chat room you mention relevant? And who are "we" you speak of? You are presenting yourself as some kind of authority, but you need to back that claim up.
I assume “we” refers to the aforementioned community on Discord. I would hardly call that a claim to authority; it’s closer to, “my friends and I think this is bunk.”
That’s not to be dismissive of their opinion, but I don’t think it’s accurate to call it a claim to authority. It’s the same as saying “a channel on IRC” or “a group on WhatsApp.”
Either way, we think that the title "this destroys the RSA cryptosystem" is sensationalistic and probably incorrect. It is presumably based on the fact that the paper claims to reduce some forms of integer factorisation to a lattice problem which can be solved in polynomial time. However, whether this technique applies in the general case to RSA moduli is not argued here and the claim seems to be premature.
