Came here to say this as well.
It took decades for effects of personal computing to show up in aggregate statistics.
See:
https://en.wikipedia.org/wiki/Productivity_paradox and https://dl.acm.org/doi/10.1145/163298.163309
edit: My comment is not exactly right, its more about general computing rather than personal computing
Someone should add a 2025–2045 section in the Wikipedia page of Productivity Paradox
The decade ahead is going to be a very interesting one
So this was about personal computing ? not computing per se ? I'd assume that by 87, the idea of digital computers benefits would be a non-question.
