How could joysticks replace keyboards apart from forcing you to use a virtual keyboard with a joystick? Is everything else about computing the same or is it some form of fantasy joystick centered computer? Anyway what’s more important is that joysticks already exist in computing and we know they serve a specific purpose and really suck for the rest cause we tried. We designed the computer after all so we control how we interact with them. Not like we found them in the wilds and they somehow only had a joystick.

Playing music has basically no skill ceiling.
