I still have nightmares from having adopted Thunderbolt 3 early when it was new (Lenovo T480 with TB3 dock). Tons of issues.
And my Surface Laptop 4 doesn’t even have Thunderbolt! But that’s a pathetic failure on Microsoft’s part.
Point being, Thunderbolt is amazing but in a very narrow usage corridor. When it works it’s amazing. When it doesn’t, jokes on you spending $90 on that single cable. I remember an LTT video on I think TB4, testing various combinations of devices and validating (in)compatibility, and spending a lot of time on Lenovo forums for support.

Why the hurry? In the last few years ssd and usb speeds skyrocketed (heatsinks too). Who needs these fast interfaces?
A coincidence this is announced on the same day as an Apple presentation....
