The compilers did arrive, but obviously too late. Modern pipeline optimization and register scheduling in gcc & LLVM is wildly more sophisticated than anything people were imagining in 2001.
But modern CPUs have even more capabilities on re-ordering/OOO execution and other "live" scheduling work. They will always have more information available than a ahead-of-time static scheduling from the compiler, as so much is data dependent. If it wasn't worth it they would be slashing those capabilities instead.
Statically scheduled/in order stuff is still relegated to pretty much microcontroller, or specific numeric workloads. For general computation, it still seems like a poor fit.
That's true. But if anything that cuts in the opposite direction in the argument: modern CPUs are doing all that optimization in hardware, at runtime. In software it's a no-brainer in comparison.
