PC World has an article on why USB-C has not been a viable alternative for the 3.5mm audio jack. Problems with USB-C include variable handling of digital to audio conversion, incompatible SOCs inside the cable, and non-standard analog-passthrough. In short, the cables which contain computers themselves are not standardized in behavior and the author's conclusion is that mobile devices must have 3.5mm jacks until the USB-C cable technology gets sorted out enough that they become usable.

First: I do NOT want the headphone jack to go away. I've used it for years. It is great for phone conversations.
Bluetooth headphones add latency. You can never get back latency. It is already bad enough on modern cell phones without bluetooth.
For years, I have had (self powered) speakers plugged into the headphone jack at night to listen while I sleep. (side note: it is amazing how durable smartphone headphone jacks are! but treat them carefully)
Recently I decided to get a decent bluetooth cordless speaker, about $40 ish. That works great and saves wear on the headphone jack. Thus I can expect a long life from the headphone jack for phone conversations with a wired headset. Any latency added by a bluetooth speaker is not a problem.
