Mics are still pretty simple though. Cameras have all kinds of onboard computing, and often built-in mics are more advanced although lacking the quality you can only get with larger size.

If mics advanced like cameras, wireless handhelds would have IR time of flight sensors that adjust the EQ to cancel out proximity effect, remove handling noise, and automatically detect feedback. They'd probably also have a tuner since they'd need a display anyway for all the extras, and they'd have modeling to pretend to be different mics built in.

But at least VocoPro made decent wireless mics affordable.
