Does Valve plan on doing anything with Source 2 in the coming years? If so, what?

We are continuing to use Source 2 as our primary game development environment. Aside from moving Dota 2 to the engine recently, we are are using it as the foundation of some unannounced products. We would like to have everyone working on games here at Valve to eventually be using the same engine. We also intend to continue to make the Source 2 engine work available to the broad developer community as we go, and to make it available free of charge.

The big thing right now is broadening the range of options we have in creating experiences. We think investing in hardware will give us those options. The knuckles controller is being designed at the same time as we’re designing our own VR games.

Much more narrowly, some of us are thinking about some of the AI work that is being hyped right now. Simplistically we have lots of data and compute capability that looks like the kinds of areas where machine learning should work well.

Personally I’m looking at research in brain-computer interfaces.
