(This isn't a criticism because I think the era of spreadsheets being super important is over, but I find it interesting that spreadsheets used to be super important.)

It's not just that computation starts with spreadsheets. Instead, written language begins with spreadsheets, as does commerce. And, ideas like zero, negative numbers, hedging, insurance, & futures are basically the result of spreadsheet innovation rather than the other way around.
