This isn’t a new phenomena: the word ‘computer’ originally described a human occupation, perhaps the first major ‘mental’ occupation to be completely automated.
That started around WW2, so this general trend can be seen for the last 75 years or so. I’d look at the fraction of the economy going into computing, as how that has changed over time is due to the interplay between the various effects of automation.
