I mean there is something to be said for KISS (keep it simple stupid) principles. Especially in an environment that is very unforgiving. In fact in SCUBA there is even a rebreather named as such [1].

And something like an xbox controller is both well engineered and quite intuitive. That said...you are going to want redundancy.

For example I believe SpaceX Dragon uses largely off the shelf computers running linux [2], and not the older rad hardened versions many other space programs require. That said...they also setup them as a to work in triplicate to ensure quorum on the data validity and then have a backup set fo computer in case they cant get quorum out of the primary.

It's even funnier than that. Appearently, for drones they made drone pilots design their optimal input device, and the result was basically a replica of a commonly used Xbox controller. The legal department was dumbfounded because there's obviously protections for an Xbox controller and they just resorted back to the original.

military used Xbox controller

Isn’t the Xbox controller only used for the periscope?
