It's attractive to deal in absolutes, but also dangerous. When C came 
about, naysayers complained that it was consistently 30% slower than 
assembler, and generated larger code by an even higher margin. Then, 
some asked, what would you choose, one OS that's cool because it's 
written in C, or one that's one third faster? and so on. What people 
have forgotten by now is that C *was* high level. And it *did* incur a 
performance hit. It also had desirable properties that overcame that hit.

Probably the worst thing that could happen to that description is it 
Kafka-esquely morphing into a dogma.
