Discord seems incredibly well-positioned to take on Steam directly. They've got huge adoption in the gamer community. They're great at the community management side of things, as far as I can tell. They've figured out how to provide a better voice experience than pretty much any other service out there, so they're smart. If it's possible to provide the same thing that Steam does at less cost (which I strongly suspect it is), Discord could do it and probably make a killing at it.
And they'd save game developers a ton of money.

Admittedly my usage is low. However twice I have encountered installer errors regarding permission issues
It turned out origin never created the root installation folder. Manually creating it yielded a successful install. WAT?!
I won't be buying anything further requiring origin until 2019 at the earliest.
It remains to be seen whether Activision/Blizzard will open up their platform to independent third parties.
At this point, the only way a competitor has a fighting chance is if Origin or Blizzard starts opening up to third party games. Blizzard did that with Destiny 2 but it seems like they might only want to partner up with high quality dev work (whereas Steam is littered with shovelware made on RPG Maker).
