True, but that doesn't mean runtime portability isn't a good thing to aim for.
It means that compromising performance to obtain runtime portability
that does not actually exist is a poor bargain.

Fight back harder. Jamie is wrong

The 50% being rather squishy, but yes this is true. Its only vaguely
