> JITs use intrinsics to work around inefficiency of generated code when the maintenance burden of the intrinsic is worth the performance boost, and the grand plan is to make a VM so terrible that you need a shitload of intrinsics for programs to terminate before the heat death of the universe?

Put it this way: the JVM is perhaps the most sophisticated JIT on the planet, maybe a million lines of code, the product of decades of programming research and billions of programmer-hours, and it still needs intrinsics to improve performance. So how about we skip the billions of programmer hours and just use lots of intrinsics?

I don't know if it's going to work, but it's interesting enough to be worth a try.
