The key word that I am objecting to is always. Trade-offs aren't some law of physics, and when they do it isn't in some cartoon way that always balances out.

The key word that I am objecting to is always. Trade-offs aren't some law of physics, and when they do it isn't in some cartoon way that always balances out. Having trisomy 21 or exons in your myosin genes don't give you superpowers in another part of your life. There are people with excellent memory and social skills, and people that lack both. By way of analogy, nobody would say that all possible airplane designs are equal and there are only trade-offs. Some are superior in every possible respect to others.
