I wasn't disappointed. There must have been a Euclid on Psychlo, too. If J steps out of line, he'll press a button on his remote and blow their heads off.
Leverage is clearly necessary.
If he wants Johnny to learn how to speak Psychlo and operate mining equipment, why would he strap him into a learning machine that teaches him not only that, but all known Psychlo history, science, tradition, math, weaponry, etc. Well, the books at least were in a blown up library in Denver. The rest were in Kentucky, I believe. But come on. No rust, no dust, hardly a cobweb.
