Sure they did, but the universe invented better idiots
Of course. However, the incompletely-experienced often choose to force bypass that configuration. For example, a lot of systems aliased rm to "rm -i" by default, which would force interactive confirmations. People would then say "UGH, I hate having to do this" and add their own customisations to their shells/profiles etc:
alias rm=rm -f
Lo and behold, now no silly confirmations, regardless of stupidity/typos/etc.
