I appreciated how Gemma was both Iron Man/Tony Stark (makes spoilers:end of spoilers in high school, then later M3gan)
robotics controlled by remote controlled by movement
and Elon Musk/Phony Stark (didn't even consider or seem to be aware of Asimov's Three Laws, programmed no safeguards against violence, seemingly gave M3gan remote access for electronics way beyond design specs, made her hyper durable, generally not able to foresee personal consequences).
