“Later on I’ll show complexity of other problems in this area and NP-Complete is actually pretty good.”

It’s really sad shit like this is getting increasingly normalized in our industry. Even a year ago when this platform was full of this kind of commentary you could take solace in the fact it was rare on tech twitter. I can’t go 15 minutes without seeing a slur in comments

"The only thing that a reader can see is whether you brought new understanding. Any remaining credit is in how you communicate. The credit for coming up with the research is now shared across the entire field because the machines exploit all of our ideas at once. And in their thinking, mulling, and regurgitating they even forget where the ideas they used came from."

first experience where ai overview and the "pre-ai" component disagree and **the ai overview is the correct one**

This is what I have been telling everyone who will listen. The most valuable thing the frontier labs can now do for crypto (and math more broadly) is publish their *negative* results. What ideas they tried, how much compute they used, and what obstacles they found.

Replying to @matthew_d_green
And specifically for cryptanalysts who are working with models and for the labs: Folks, what we need right now are *negative* results. Silence is the worst thing you could be publishing.

We implemented 1024-bit RSA signature forgery in nearly SNFS time! Temporary access to an HSM allows an attacker to forge arbitrary signatures (without factoring). Join work with Laura (1st author!), Adam, Nadia, and Emmanuel github.com/ucsd-hacc/NSNFSSS…
