Valve fascinates me because the devs there occasionally seem to be simply the best on earth in a given field, but despite that, bizarre bugs will persist for a long time. My favorite was how steam in home streaming from a PC to a steam deck wouldn't work if the steam deck had an Ethernet and wifi connection - one of the connections had to be disabled or the stream would always crash.
Maybe they need a few average devs there to spend time sweeping up behind the paragons that are pushing the envelope into these features existing at all.
Valve famously has a very flat org structure so it's possible that that problem just isn't sexy enough for someone to pick it up on their own, without being told by a higher-up.
I wish they offered remote; I'd happily work there doing those sorts of unglamorous bug fixes. High-reliability engineering is my jam.
My favorite bug family, that somehow to sneak in every time, is how their react frontend (or whatever the store runs) manages to semi-crash and the controller inputs are no longer recognized.
I kind of hope at least they'll fix such issues permanently before the steam machine release.
