"The Birth and Death of JavaScript" predicted the future
The first time I watched that talk, I was very drunk, and forgot about the framing device halfway through. I went looking for Metal as if it was an actual project. It was not far-off from what I expected to be possible, having longed for a way to weld an emulator to Wine and run small Windows programs in Android. My shorthand was Turing completion. The man says any computer could run any program, and I wanted could to become can.
Now there's a whole class of "usermode emulators" and you can play Crysis on your phone. The original, unmodified, full-fat Crysis.
