Your statement "Of course wireless is the future" has no relevance to what I posted - I am not disputing that statement at all. Also, calm down on the "everything is a conspiracy" train.
To add, I wasn't even replying to the OP, but to a specific post which seemed to incline (unless I misread it) that in the future the phone might have NO ports. I believe it will always have one port, be it USB-C or Lightning (at the moment I'd wager it will remain lightning but it might become USB-C).
Also regarding the in-flight stuff, I wasn't referring to interference with planes... People might run out of battery on wireless devices, so may prefer to have wired back-ups. If you are on a long flight, you may not want to rely on bluetooth earphones.
People might also find transfer speeds are a lot quicker via wired (and reliable), compared to having to rely on bluetooth. I can say from experience, iTunes is a nightmare and much slower when connecting via wireless compared to wired.
There are also many other arguments to have at least 1 port on a phone, regarding many peripherals which cannot connect wirelessly, either due to hardware limitation or due to loss of function and/or quality.
