> Not saying I'd trust my life to a gamepad alone

I’d trust it to an Xbox, PlayStation controller, they’re some of the most reliability tested input devices ever. Most people are freaking out because it’s some known glitchy budget gamepad.

From a functional safety perspective if you can't verify each step from the initial risk assessment to the final product, you can't prove the overall risk reduction and therefore don't know the overall residual hazard. From that perspective this sub would never have left dry dock (or possibly the CAD model).

In practical terms if push came to shove, an Xbox or PS controller is probably more reliable than most equivalent devices. My stock phrase when comparing normal functions with Safety Instrumented Functions is "I'd trust this with my car, but not my life."

My playstation controller of less than a year old has stick drift so ymmv and you definately need backups. N=1 ofcourse but it's not that rare.

PS1 PS2 PS3 PS4 PS5 had two controllers each system, no drift or weirdness.

Yeah someone must have it but we’re talking most of my life here no issues, I’d trust these controllers.
