Not just startups or funding. Google alone has more AI compute than China and the EU combined.
There's no shortage of capital in Europe. But nobody wants to take the risk. Meanwhile in the US, people are putting 10-100x the capital at risk. So you can say what you want about it looking scary to you to invest in the US, but the people with capital to invest clearly don't see it that way.
More often when you hear VCs give interviews, they are saying the opposite: that never-ending EU regulations introduce more business risk than anything the US president could possibly do.
I’m not all that convinced on the regulation part.
Ultimately it’s all about investing money to create real assets that generate cash flows. One can side step regulations to some extent whilst developing a product (nobody cares/notices until you are actually growing fast) and then deal with regulations later. Uber already showed this and the leading AI firms are following the same act - having ripped off a lot of content but nobody threw a fit until a legit asset came out of it.
