I would agree, but i really don't know if this happens. top usbc can endure 120-240W and 40gigabits/s and I am not sure we've even hit the limits, some Chinese brands had mock phones with abnormal charging speeds (at least I'm about sure 120w). Like I can't imagine what new features some port could bring, that we'll want in a phone that fits in our pockets. The only thing changin imo is maybe a new fancy more durable form factor, but I can't say usb-c is that bad in this direction
And as it is it seems extremely unlikely that Apple wasn't already planning Lightning for iPhone...
