Yep.
Burning Investor money : OK
Transmitting power through sound: OK
Increasing distance, and adding focusing through phased arrays : OK
Adding a localization possibility (probably by TOF triangulation on elements of the array, of with array scanning and probing - A kind of sonar.): OK
Increasing power to levels where even the air is non linear : No way to give that into the hands of a customer. Not safe.
Arguing it locates the phone to focus the energy to it and not damage your body ? No Way. Functional safety does not work without proved guarantee.
Accepting 99% loss ? No Way. (50 million phone chargers * 500W loss -> 25 GW equivalent to 20 brand new nuclear plants generating waste)
User accepting the limitations in orientation and free line of sight requirements ? No Way.
Trying to compete with that crazy expensive double phased array bricks setup against two flat 30 cent copper coils : No way.
Conclusion : It won't happen. You can't just ignore physics, ergonomics, Safety, and economics and also make a successful product
