>how hard it must be to make a “decent” thunderbolt dock.
I’d been thinking about this and want to add to the evidence that even though MacBooks were USB-C only for years and years Apple never shipped a dock they only shipped single port dongles.
No way would Apple not sell a $500-$800 dock that could “solve the usb-c problem” unless there was a good reason and I think the reason is this solution is inherently janky for some unsolvable engineering reason and only single port cables are reliable to the level Apple was happy with.
