From what i gather the red flags are

- coreweave used the initial investment to buy gpus and put them in existing datacenters, rather than building new datacenters from scratch

- nscale is very behind on their planned datacenter, and will miss the deadline

- coreweaves new datacenter in partnership with datavita is probably on track, but its not clear how datavita will get the 1GW of energy to run it

I lean towards AI skepticism, but these dont seem thay bad to me. My guess would be the first 2 are the promises of silicon valley velocity hurtling headfirst into european administrative process.

And the third seems like just the challenge the firm has taken on, which could be solved with huge solar plant or something. We wont know until they try. Which is ambitious but theres nothing wrong with that.

If there were credible red flags as to the demand for the supply these datacenters will generate, or the projected 47b boost to the economy if that supply were produced, then thered be real cause to doubt. Because the whole value chain might not be well thought out. And thays the part i personally am not entirely sure about.

But if thats fine then just being negative because the companies didnt meet their how ambitions is a bit cruel. And this sort of attitude will just suffocate any silicon valley style dynamism that europe might be hoping to cultivate
