It's not even software bugs, just bad design. As technology has gotten more complex we haven't really kept up with quality, imo. For example Google home devices that I have, such as the nest displays and nest minis are absolute crap. At first they worked fine, but bad antenna design means that their wifi connection is absolutely terrible. The nest displays after operating for some time just turn into laggy messes. Both my Macbook and my Windows machine (gaming) have random issues that pop up now and then. Firefox has a longstanding bug where using location causes wifi SSID scans to be spammed endlessly resulting in periodic 10s lag spikes for all networking on the entire machine (& I'm sure Chrome has similarly bad bugs), fixed by doing a Firefox "refresh" where it keeps data but reinstalls itself. Pretty much all software lacks the options we want, in the places we want them to be and requirements can differ completely from person to person. It's a really tough problem to solve to be honest. Sure bugs can be fixed, but some bugs only impact 0.5% of users and some "bugs" are just bad UI/UX and are bugs to some people but not others.
