I'm not a fan of people thinking Gabe does everything, from haters and lovers alike (though, based on what I'll say, there's maybe more reason to hate Gabe for getting the credit). We need more appreciation for the current Valve team, especially the engineers who made Steam Deck and all the Steam features happen.

If Gabe dies, whoever gets the reins (kid or close friend) literally just has to do nothing, and the team just has to keep getting younger likeminded folk onboard.

This isn't a Nintendo situation where most higher ups are greedy bastards and Satoru Iwata had to hold all of them off.
