They’re still going the almost certainly end up running this on US designed chips, with US designed networking equipment and a bunch of other assets tied back to US companies. They should do what they want, but it’s “sovereignty theater” at best.

You always have to start somewhere. Whether this will succeed or not is not known, but you do have to start somewhere.

I wouldn't say that. I think it's a proportional response to US tarriffs/changes in foreign policy under the current administration, just like the cancellation of defence contracts/orders.

It's unrealistic for any nation to do everything themselves, but they can make some changes in response to the US starting trade wars, ditching foreign policy/climate objectives, etc...

The US or Trump can’t switch off your chips or your networking equipment on a whim - and if they ever designed hardware that could do that, no one would buy such hardware as soon as that capability became known. Using cloud software is a much bigger risk - your access can be turned off anytime and data access is part of the deal.

Sovereignty is not about building everything yourself. Division of labor advances civilization, but it doesn’t have to come at the cost of sovereignty. Sovereignty is about designing the work contract such that you don’t become entirely beholden to another party. You build hardware for me, but after that it’s mine, not yours. I trust you to build the hardware to fulfill that contract, and if you ever break that trust I’ll find someone else to build that hardware. That’s sovereignty. I don’t have to build everything myself.

Maybe, but chips cannot hold you hostage during work. I don't care where things are built (except when they are built somewhere where human rights are being treated like shit), software is what locks you into whatever bullshit the company decides on, not chips. So it is a good step I think. We don't have to be all "we don't use anything from outside the EU" - why? Some countries are better than others at stuff. Fair enough. The movement is about moving away from software monopolies that decide on what you can and can't do, not about having everything inside a certain geographical location.
