Sadly the UK has a long history of underinvesting in cutting edge tech, from aerospace (https://en.wikipedia.org/wiki/BAC_TSR-2 https://en.wikipedia.org/wiki/British_Aerospace_HOTOL further development of Concorde)

to transport (https://en.wikipedia.org/wiki/Advanced_Passenger_Train https://en.wikipedia.org/wiki/Tracked_Hovercraft https://en.wikipedia.org/wiki/Hovertravel https://en.wikipedia.org/wiki/Sinclair_C5 https://en.wikipedia.org/wiki/Maglev#Birmingham,_United_King...)

to chip design (https://en.wikipedia.org/wiki/Inmos transputer, static RAM, VGA standard).

Interestingly, the 3 British designers who made up Flare Technology, had a big influence on console and computer designs in the 80s/90s: They were responsible for the ZX Spectrum (partly), Konix Multisystem, Atari Falcon, ATW (and Blossom graphics card), Atari Jaguar, Super FX chip, Nuon
