> Microsoft excel driving an astonishingly large number of business processes.

I'm not sure I agree. Google obviously felt that they needed an office suite (including a spreadsheet) in order to avoid being frozen out of some markets (so they bought one), but none of the other Big Tech players felt the same way, nor does the lack of one seem to have actually limited their growth, and the current crop of low-code and no-code tool entrants don't seem to be predicated on Excel as a starting point.
