Not every country is in a crypto-libertarian race to hoard power and wealth.

Meanwhile, in the EU, the model would be collectively financed, trained by a competent, neutral agency... and then completely lobotomized in the name of "the children," "safety," "IP rights," "correct speech," dozens of individual countries' legal and regulatory requirements, and any number of additional vocal, noncontributing NGOs.

So no one would get rich off of the public model, but no one would get much of anything else out of it, either.

As another reply suggests, there's a reason why things happen in the USA first. Even when they don't, the prime movers move here as soon as they can. Or at least they used to.
