I don't have much faith in future processors if it really is impractical to make optimizing compilers for them.

  Well, that's happened in the past. Itanium and the Cell made it to volume production while presenting extremely hard problems for a compiler. I once met the group from HP who were trying to write an optimizing Itanium compiler. It wasn't going well at all. The Itanium could execute several instructions simultaneously, but the compiler had to block them together and specify this. About a hundred instructions at a time had to be scheduled together to get decent optimization.
