I have a dream of a future where all technology is modular, easily replacable, and recyclable.
You phone screen broke? Just replace it and recycle the old one. Your laptop's getting a little slow? Replace the CPU.
This would also require a set of universal adaptors and fittings, so that everything would be compatible with everything else.
And I honestly don't feel like this is a lot to ask?
@InvaderXan BUT MONEY!
This seems like actually sensible stuff that makes sense but how would large corporations get filthy rich if you can just replace a screen and not buy an entire new phone?
USB is convenient only insofar as you don't have to worry about where in the processor's address space to put them. The technology that enabled 12Mbps throughput on USB-1 allows 12Mbps data rates on RS232 ports as well, and being point to point, is easier to both code for and design new hardware for.
