Source: I was Cloudflare's CTO.
I worked with 2 of the cofounders at their previous company and some of the original prototype was written at my apartment at the time.
I don't know you from a grain of salt, but you've seemed to be pretty open and honest on HN about some of the inner workings (technically and politically) of Cloudflare, which is appreciated.
2) You're targeting to the wrong person. Blame the managers at Netscape for pushing Brendan Eich into creating JS, rather than letting him use Scheme as the scripting language. From there, it would've made sense to allow Scheme to be compiled into bytecode.
I'd also say that when you look at JITed language like Lua and JavaScript the performance is pretty damn impressive. As with so many things it depends what you're doing.
