Earlier quoted context omitted.
Part of the problem with electronics is often a brand new unit costs less than replacing a faulty part on an old unit due to miniaturization and having everything on chip combined with economics of scale. Still it’s a worthwhile pursuit. At some point pocket PCs/phones will be good enough, just as for many a 2014 laptop is still good enough.
They already are. Phones from 2016 for example feel completely usable today. That goes for the repairable ones at least, like the LG G5, but even the older LG G3 holds up well. If all modern phones were as repairable as those we could eliminate so much garbage!
The problem is that this has happened despite my usage not changing.
