Honestly, I haven’t heard much from WebAssembly in several months, so I was figured they were still quite a ways off. Several big engines, like Unreal Engine 4, not really putting their weight behind HTML5 as much as they were about three years ago, during the Windows 8– and iOS-era. Now I see the above video, which starts with Tim Sweeney and goes on to include others from Mozilla, Autodesk, and Unity, and I am starting to assume that I just wasn’t looking in the right areas.
According to the video, though, it sounds like application startup time is the primary reason for shipping WebAssembly. That could just be what they feel the consumer-facing message should convey, though. I should probably poke around and see what some web and game developer contacts think about WebAssembly.
