I mean I see what you are saying but in the case of spell check and driverless cars you aren’t replacing the dumb version with the smart version you are augmenting it. If your spell checker fails you can still manually do it without any friction. I think some people get wayyy to reliant on using spell check though (especially with the right click to replace etc, so they never have to actually learn to spell the word).
