The sheer magnitude of the ports assimilation into modern society will be one they won’t be able to shake off over the course of a couple years but I can see the tide shifting eventually. Even with Apples marketing team flashing the death of “100 year old” tech. The core concepts of audio reproduction remain no matter how hard you try and shake it off.
When looking closer and really considering what Apple has done today, the only people that will be frustrated about the missing headphone jack in the long term will be music lovers like myself who want and sometimes need to have the flexibility and ubiquitous acceptability of a universal analog port for audio output.
