Why cant there be a universal cable for every kind of socket?

Question

To elaborate: Why must a USB cable look different from an HDMI cable? Why must we have B-type and C-type chargers? Why use circular audio jacks when it can be “USB’ed” instead? and so on

Answer 1

USB C will replace these things in the long term. It just takes time

There’s been a few monitors that use USB C (e.g. LG UltraFine). But otherwise you can get a USB C to HDMI cable

You can do audio over USB C too – but manufacturers seem to have gone the fully wireless route

As for the power issue people mention, I’m pretty sure it’s wrong. USB C negotiates power delivery between devices, so if there’s no agreement to provide power, there wont be any power provided
