- To my mind that's more evidence for why it can't be the fundamental
- theory of physics, at least in its present form. This is a purely
- "esthetic" argument, though, based on the prejudice that the laws of
- nature should be simple, so I don't take it too seriously.

- It's worth noting also that Newtonian mechanics was only comprehensible
- to a tiny coterie of people when it was first developed. Later,
- education brought it within the grasp of many people, although lately in
- America the set of people who can understand it is dwindling back to a
- tiny coterie again. My point is that Newtonian mechanics or string
- theory is not actually nearly as complicated as the skill of, say, being
- a politician and fooling most of the people most of the time. Work in
- AI has shown that often the things we THINK are hard to do are easier to
- teach a computer to do than the things we think are easy. It's just
- that people more commonly use their intelligence on social skills than
- on math and physics.

- It's probably both. I imagine that the basic laws are very simple but
- deducing all their consequences is essentially impossible.
