Excepting for all of the drawers now full of obsoleted Apple Lightning cables. Will they also migrate into the landfills just like the untold numbers of USB-A, Firewire 400 & 800, Display port, Apple ADB, parallel, RS-232, Micro usb etc cables residing there now? We are now at CAT 7 ethernet cables. What happened to all of the prior generations of ethernet cables? Were did all of the Apple 5 watt power cubes, Firewire 400 & 800 power cubes and other obsoleted wall warts go? Where did all of the "plastic cased" Apple computers end up? Since 1984 there have been lots of those made.
Apple milked Lightning as hard and as long as they could. Now it will be proprietary USB cables requiring their power bricks.
Now the eco friendly solution might be send in the Lightning cables and they will be replaced with USB-C cables. Same with the wall warts. Chance of that happening ranges from slim to none.
