> Bluetooth reminds me a lot of the F-35: Designed to do everything, does none of it particularly well, hard to build/maintain, and frankly would have been better off as three or four competing standards that did their "thing" well and nothing else.
Hard disagree. Bluetooth has an important disadvantage, in that its quality is bad. But it's also got an important advantage: it works, at all.
Basically anything made from early 00s onwards will be able to connect to a modern pair of Bluetooth headphones. Interop is the selling feature.
