I wish one of them would just try and release a 180nm process in a way that allows public domain maskset distribution.
If it flops, so be it; if not, many people like myself can suddenly start hacking on analog or mixed IC designs for potentially exotic things, like analog-computer-based UAV controllers that integrate the control loop with e.g. external feedback like simple doppler/chirp radar to reach microseconds of feedback latency and thus enabling monolithic closed-loop control.
A miniaturized version of https://www.research-drone.com/en/ https://www.research-drone.com/en/ with the blade's counterweight being a single neodymium magnet in an outrunner configuration and a ferrite stator fabricated using SMD inductor technology to target the 5g (+ payload + battery) UAV class would be interesting, but the ~3KHz (typical disc loading and high subsonic tip speed) rotation rate (~200k rpm) make software control of the motor driver difficult.
