I read an article from 2021 that stated the UK's "robot density" (the number of robots per ten thousand workers) was the lowest in the G7.

History has shown the UK to traditionally be intentionally adverse to invest in her infrastructure, even when the workshop of the world. Presently a service based economy, the UK would not top any list within Europe, but does she need to ?

My question is how are such numbers reliably compiled and what level of efficiency is the tipping point relative to the economy ?
