"It will work". Just as bluetooth? Humanity has serious issues getting serial to work over USB, yet this will just work? Across all OSes? We can't even make USB-C
CABLES correctly, but THIS is a sure thing? Even the cheap ones
everyone will buy? Or the expensive ones that has the same hardware but a nicer box/cable?
We won't have apple compatible cables, android compatible cables etc.? We won't have situations where that popular brand of "cables" doesn't work on new Samsungs/xxx?
Let's pretend that will be the case this time around?
Honestly I think audio enthusiasts are the only users for which that isn't the most absurd idea ever. Audio enthusiasts could use a decent DAC and for the first time combine regular hardware (wide selection of phones) and still get decent output. For everyone else though a headphone jack would be several orders of magnitudes better and cheaper. And guess what, it just works. I know people have done their darndest to make the microphone over 3.5mm experience as miserable as possible but despite that we still have/had a universal way to transmit stereo audio.
There are no decent alternatives even on the horizon. There haven't been brought up a single argument for the removal of it other than it isn't so bad to spend 10% of the device on adapters that you always need to carry. Seriously?
