You can still use HDMI etc for video.

Wireless is close enough to the fastest possible USB speeds not to worry about it and much faster than the slowest USB speeds.

Wireless isn’t “close enough” for charging larger phone batteries.

I travel a lot for business and I will soon be doing the digital nomad thing flying across the United States. I use a portable monitor that is both powered via USB C and does video over USB C.

I also have a few of these truly “universal” USB C cables.

A 40$ cable with 5 dongles is a great argument that USB is fine.

As to wireless, an iPhone 13 pro max can do 15W wireless vs up to 27W with the right USB charger or 2W USB if you happen to plug into the wrong charger without thinking about it. In practice I only charge overnight or while driving so it’s hard to see a practical difference.
