Drones, in the form of a jetpack.

A little joystick in each hand with DJI levels of KISS, and with the same DJI "Help I'm out of control!" button too. Probably "return to home" too.

We don't/can't have that, because there's no servo-mechanical joints to be controlled in the referenced rocket pack system.
