No. A smart programmer will consider each optimization on its own
merits. Some optimizations will hurt more than they help, and the
programmer will leave them to the compiler for each machine. Some
optimizations are worth a conditional definition. Some optimizations
are always worthwhile. Only a blind programmer will ignore hand
optimization if he cares about efficiency.
