As someone that didn't like originally giving up my ports and thought Jony Ive was a bit too overzealous with thinness, I actually don't think he was wrong.
USB-C is pretty great, and the sooner we shift things over the better. When I bough a MBP with only USB-C ports I just bought a little dongle thing that slots in to my two ports on the side and gives me USB-A, HDMI, SD and MicroSD. I've used the thing around 20 times and its never been a burden because I carry it with me in my laptops case.
At this point I actually see adding the other ports back as a step backwards. HDMI is old and aggressively large in 2021. My 3 devices that use an SD card actually use a microSD card so I need to carry around an adapter anyway.
It almost has, it's just playing the long long game. People don't replace their monitors, tvs and projectors constantly but eventually they will all be bundled in with usb-c cables. Last time I was in an office, every cable had a usb-c dongle stuck to it permanently.
