Big picture, USB-C is set to considerably reduce ewaste given that more and more consumer electronics products are standardizing on it as a charging solution, eliminating custom chargers and letting manufacturers get away with not including a charger. This is likely to be accelerated by regulations in the EU. The last time we had this level of standardization was probably the AA battery. Not saying things are perfect (because they obviously aren't) but computers - and especially finicky docks and high performance cables - are just one part of a much much bigger market for USB-C.
