I can't always tell what's a joke, does he actually believe people would write software to compile to ASM instead of javascript because there are a few WTFs on js's "hashmaps." Much likely a newer version will come out before 2035? Or was that a joke?
I also feel like poking fun at "yavascript" at a python conference is cheap and plays to an audience's basest desires.
Really I see a mixture of the following: - Predictions about the future, some of which are just cleary jokes (e.g. 5 year war) - Insulting javascript preferring clojure - Talking about weird shit you could, but never would do with ASM js - Talking about a library that allegedly runs native code 4% faster in some benchmarks, with a simplistic explanation about overhead from ring0 to ring3 overhead.
