If everything adapt the pc building modular approach we would be in a much better place, some of the replaceable components are already modular if you see the ifixit tear down, it’s just that the manufacturer spends more time trying to ruin your chance at properly open it without damage other parts. Same thing for many electronics, the opening part are the worst as you can damage the casing(crack the clips bent stuff, broke the ribbon etc) or some one way bs. Even opening a freaking hair dryer to clean up the internals is a challenge.
