Does anyone else feel like ePrint is accepting too much garbage these days? While occasional errors are inevitable, it seems to me that the problem is more systematic now. Or maybe there has been a change of policy?

Nice popular explainer on threats quantum computing poses to classical encryption. A bit sensationalistic, but not too inaccurate — especially on how long it’ll take to update legacy systems in healthcare, energy, finance, and government. www.wired.com/story/q-day-...
The Quantum Apocalypse Is Coming. Be Very Afraid
What happens when quantum computers can finally crack encryption and break into the world’s best-kept secrets? It’s called Q-Day—the worst holiday maybe ever.

If there's one lesson to be learned from the DeepSeek story, when it comes to hardware vs algorithms, always bet on the algorithms.

Indeed! Using Gen AI for search is like getting a new hammer and becoming so excited by it that you start using it for screws and drilling.
At The Verge, @lopatto.bsky.social reports on how AI-generated answers to search queries are feeding into “the large-scale degradation of our information environment,” and asks: “What good is an answer machine that nobody can trust?” www.theverge.com/2024/12/5/24...
Stop using generative AI as a search engine
Sometimes ChatGPT spits out something original — and wrong, like fake presidential pardons.
