Yes, it's fine to give up the lead in any one subsector, but Europe is so far behind in tech industries in general. It's not just cloud services or self driving cars, look at SpaceX and Starlink: Europe has no equivalent to either, and is many years from gaining one (I'm aware of some plans, but they're far away from being able to actually launch, and some are dubious besides).
Both major smartphones OSes? Run by American companies. Major desktop OSes? Two by American companies, one originally started by a Finn, who still manages it...and he moved to Oregon.
But you don't have to take an American's word for it, just read Mario Draghi's report. The man loves Europe, deeply understands the European economy, and has a whole lot to say: https://en.m.wikipedia.org/wiki/Draghi_report
