Worth keeping in mind that the UK is third for tech after the US and China. Like, it'd be ridiculous to say the UK stands a chance of properly competing with the US, but it outcompetes basically everyone else who isn't a continent-scale megastate.
Seems kind of irrelevant as an employee; my coworkers who went to a Chinese employer have regrets. Working for the hotel California I've had happy coworkers in Canada, Ireland, Netherlands, Switzerland, Czech Republic and Italy.
