The UK didn't exactly get left out, it just failed to invest in growth and productisation. Some great research comes out of there and then moves overseas or gets bought up (like ARM).

If there are any chips on shoulders, it's more to do with the government talking itself up, throwing around some feel-good bullshit, usually entirely mis-targeted (see for example Sunak talking about making a safe space for blockchain companies) and then failing to get out of the way when the country actually does produce something amazing.
