I curious, maybe AI learn too much code from human writed compilers.
What if invent a fresh new language, and let AI write the compiler, if the compiler works well I think that is the true intelligent.
Have a read about Servo, it is binding with SpiderMonkey as JS engine.
Is there some chance, that servo decomposed from SpiderMonkey? If it is not, I don't think anyone can tell difference between firefox and other browser use Servo.
