Where is the USB C on my iphone? Why do I need a dongle to connect my brand new I phone to my brand new MacBook? Why do the headphones that came with my iPhone not work in my MacBook?

Why does my magic mouse not charge via USB C? My keyboard? It has been years now, why hasn't this happened within the company? Shouldn't Tim Cook be banging a pot and pan outside every team's door asking why they haven't gotten with the program?
