Brown said that he has an obsession with platform ecosystems and systems engineering, and that he looks forward to continuing his work in these areas of Apple. Brown says he will "focus on all graphics applications" and work with developers who use graphics on Apple platforms.
Prior to joining Apple, Brown worked as a VR engineer on Valve's VR team, but Valve laid off the VR team earlier this year. Prior to joining Valve, Brown was one of the first engineers to join the Xbox project as early as 1

Back in 2013, Brown shared a blog post arguing that Apple TV had the potential to ruin console games thanks to be its support from third-party apps. Microsoft and other gaming platforms now support indie games, but at that time, Brown argued that Apple could have killed the Playstation and Xbox by introducing a game ecosystem for Apple TV . From Brown's 2013 blog post:
Apple, if it chooses to do so, will simply kill the Playstation, Wii-U and xBox by introducing an open 30% cut app / game ecosystem for Apple TV. I already make a lot of money on iOS – I will be the first to write apps for Apple TV when I can, and I know I will make money. I wanted xBox if I could, and I knew I wanted to make money. Maybe a "console-capable" Apple TV isn't $ 99, maybe it's $ 199, and adds another $ 79 for a controller.
Apple did not do that in 2013, but later opened Apple TV for apps and games with a dedicated Apple TV App Store. Unfortunately, Apple TV App Store has not exactly been a console killer.
It is not clear what specific graphics applications Brown will work with at Apple, and it is not known whether he will join Apple's rumors of the AR / VR team.
