Please give it some exposure. It might not result in anything even if it got 100K signatures, but if it doesn't get any it definitely won't and we're seeing more and more evidence rather than conjecture around these murky, opaque orgs.

Palantir, a US spy-tech firm, has been given access to millions of NHS patient records.
Its founder has said the NHS should be 'ripped up'.

Stop Palantir taking over our public services!
Our public services aren’t for a secretive profit-hungry US tech firm. Sign the petition to tell the Government to scrap all contracts with secretive US tech firm Palantir.

How do we figure out the circuit required to prepare a given state, and what's the best circuit? With help from MPS, these guys get it down to logarithmic depth.

This is horrific. AI hallucinates references, Google Scholar swallows them, libraries adapt their records to Google Scholar as ground truth, and an inexistent paper becomes reality.
Finally, if you can get through the paywall this piece from earlier in the week illuminates how the experience above is just a tiny part of an industrial-scale, global, and sector-wide catastrophe of AI and citations to nonexistent papers in academic publishing bsky.app/profile/mile...
Academics and technologists are sounding the alarm about a growing crisis in scholarship as we know it: AI-generated citations of nonexistent papers that have infested real journals. Despite being fake, the sources are widely assumed to be authentic the more they appear in published literature.
