How can you possibly say there are no shortcuts? On what evidence? The science only just got good enough to begin looking in the right places.

Also: discipline is a trick too, the way exercise is a trick - you're twiddling levers that were built by evolution to react to circumstances, not to intent. They're just both dumb slow tedious painful brute force tricks that work (to a strictly limited extent and far less than optimal). Better tricks would be better, don't you think?
