Google's AI research is done in London, for example. Just because the companies are listed on the US stock exchange and their headquarters are in the US, doesn't in any way show where the actual work is happening.
The UK suffers from a cultural snobbery towards technology that tends to direct UK capital away from such investments, it does not suffer from a shortage of high quality research (both commercial and private), funded from abroad, or for that matter talented individuals.
Not sure why I'm responding to this, since it's so deluded and misinformed and presumably contributed by a pro-tyranny influencing campaign.
You clearly don't understand anything about the difference between autocracy and democracy.
