Remarkable, but important to notice that the change only applies to review/survey and position papers
arXiv, a preprint publication for academic research that has become particularly important for AI research, has announced it will no longer accept computer science articles and papers that haven’t been vetted by an academic journal or a conference. Why?
A tide of AI slop.

The AWS outage bricked people's $2,700 smartbeds, leaving them in a reclining position or with the heat up. People were unable to use them, basically. A GitHub repo exists that lets people operate their beds without reliance on the normal infrastructure

The AWS Outage Bricked People’s $2,700 Smartbeds
When Amazon Web Services went offline, people lost control of their cloud-connected smart beds, getting stuck in reclined positions or roasting with the heat turned all the way up.

Our protocol is simple & modular: it works in the "Arithmetic Black Box" model, and inherits the security properties of the ABB instantiation (passive/active, static/adaptive, etc.).
Using SPDℤ₂𝑘 for ABB, we get about 20,000x and 37x better throughput and latency than SoTA for dishonest majority.

Anyone who has been an IACR member in 2023-2026 should have received a link to respond to a survey about conferences and publishing. So far over 500 people have responded, but it will remain open for responses until Sept 12, 2025. I would also encourage people to use their forum invitations.
