Well, they do have MLIR, which is probably the closest thing to "secret sauce" they've got. I'm excited by some of the performance-oriented features like tiling loops, but they'll need the multitude of optimization-hints that GCC and Clang have, too. They also have that parallel runtime, which seems similar to Cilk to me, and Python fundamentally can never have that as I understand it.
