>It's sad because folks will be less and less interested in fixing their things or simply opening their devices to understand how they work
those days are long gone. you might be able to disassemble a turntable to figure out how it works, but disassembling a phone isn't going to tell you much when all the magic is in the silicon. all you get from disassembling it is a circuit board with random bumps.
Hm, these markets in Shenzhen seem to offer different stories. Youtube is full of those, you can replace/upgrade displays, memory, storage of your phone or even assemble your own.
And in my country you have these little shops as well, where you pay a premium, but you dont have to buy a new phone.
So, unless you really want to fix something very integrated, i am rather positive about the situation.
And from my own history, mainboard was never really a problem, it was always something attached or plugged or solded onto it.
