Intrinsics aren't really C; they work in a C-like syntax, but you're still doing the exact same thing as assembly: you still have to write out every instruction you want to use, so you're not really saving any effort compared to just skipping the middleman.
In return, you are stuck with an extremely ugly syntax and a much less functional preprocessor, with the added bonus of a compiler that mangles your code.
