One tractor can do the work of tens of people easily, and in the last ~150-200 years, we've gone from a vast majority of people producing food to a tiny minority, while the rest can be social media managers and feng-shui specialist. One excell spreadsheet can do the work of a 100+ paper-based accountants, and that's even before a database and automation.

We could've stopped at tractors, lived the same lifestyle as before, but with 1-2 hours work per day (or even less), but we decided we wanted and needed more, and more is what we got.
