Compared to x86, which is wholly owned by an American duopoly and needs licensing to produce legally, boosting RISC-V is a major step towards chip independence for Europe. With the current state of the US it almost seems a necessity. The only downside here is that it didn't happen sooner.
Even if Intel licensed x86 no one in Europe would want to make them. Unless they're guaranteed a monopoly there will be no takers. European companies and conglomerates are extremely lazy and risk averse.
All they want is to suck on the government's tit.
What about ARM? Isn't it also European?
