Oculus VR has hired yet another Valve virtual reality veteran.

Just two weeks after announcing it had hired Atman Binstock, the company has now brought on longtime Valve VR developer Michael Abrash as the company’s new “Chief Scientist.” His arrival at Oculus VR comes just three days after Facebook purchased the company in a surprise $2 billion deal.

In a blog post on the Oculus VR website, Abrash laid out his prediction for what he believes is the future of virtual reality. “We’re on the cusp of what I think is not The Next Big Platform, but rather simply The Final Platform–the platform to end all platforms–and the path here has been so improbable that I can only shake my head,” he said.

The “final piece of the puzzle” to help VR go mainstream, Abrash said, was Facebook’s purchase of Oculus VR on Tuesday. Advancements to display panels requires expensive engineering, and now that Facebook is on board, Oculus VR should has the capital to make its dreams come true, Abrash claimed.

“Facebook’s acquisition of Oculus means that VR is going to happen in all its glory,” he said. “The resources and long-term commitment that Facebook brings gives Oculus the runway it needs to solve the hard problems of VR–and some of them are hard indeed. I now fully expect to spend the rest of my career pushing VR as far ahead as I can.”
