> Underwriting gigawatt data centers and frontier models demands a fully realized European Capital Markets Union, a single energy regulator with cross-border grid integration, and shared fiscal borrowing power.

Care to elaborate why you consider this an absolute must? I don't see why, say, France can't build an "AI valley" somewhere near to on of their nuclear power plants and commit to provide X amount of energy for some fixed price for a decade. To me the main reasons for not building top AI labs with frontier models in EU seems to be:

- Venture money is not there (or people controlling the money are not on board to invest into such labs).

- Weak political will from countries who could do that to actually go for it.

- Top scientist who could work on it choosing to go for much higher payouts in the US.
