Top post: @AndrewCurran_ “From the letter: 'Let us jointly explore the strategic establishment and participation of Anthropic within the European Union. With legal certainty, market access, capital and a set of values that suits this company.' 'Anthropic fits us particularly well. A company that understands the ethical use of AI not as marketing, but as a core conviction. That places safety over speed. That is a deeply European attitude. This company would not be constrained in Europe; it would be unleashed.' The UK also made similar overtures a few months ago. It won't happen. Anthropic will stay where the compute is, and where the supply is guaranteed. They can't risk getting cut off, and from here on out the compute will increasingly be concentrated within US borders.”
