Epic wants it known that they're a great place to work. They're gunning at a $100B+ valuation, and they've got a multi-trillion dollar market to capture. It helps that they own one of the biggest rendering technologies and have turned it into an entire career and marketplace. They have huge mindshare across a half dozen industries.
The last two technological waves were Internet and Smartphones. The next one is GPUs and all of the things unlocked by them: deep learning, rendering, spatial computing, etc.
Longbets: Epic surpasses Google's valuation one day. We're in the early stages of a brand new surge of innovation and investment. Imagine the browser being leapfrogged - that's where Tim Sweeny's head is.
