Or consider that the startup time of OSes still hasn't changed much. It was much faster for a while when SSDs came around, and Windows generally has become faster with their not-quite-shut-down technique. But normal bootups, around 30-60 secs on normal machines, 25 years ago and still now. And the important point is: it _is_ annoying, an actual bootup in 5 seconds is easily possible from a technical perspective, and would much improve the user experience. Take systemd, I remember it brought a lot of startup time improvements for a while, or at least promised them. I don't follow Linux very much these days, but when I do a standard installation of a popular distro - sloooow startup. Last I looked I had an issue with tons of virtual serial devices created serially, took probably 10 seconds alone. Parkinson's law at work.
