*without a random ...

Any game with a random element (dice, cards, etc) eventually becomes boring - think checkers, or tic tac toe. For those same games, only complexity made them "seem" difficult to people with limited skills The only skill in chess was memorization. Of course computers can do better.

It's just a more accurate device for the guts of an Inertial Navigation system. .

Post-employment non-compete agreements without any compensation are completely unenforceable. I'm not a lawyer, but I've talked to plenty on this very subject. I work in an industry with very stiff non-competes - When I left my last job, they made me sit out (not do any competing work) for 3 months. But they had to pay me for the privilege. And I could have given up the money and moved on sooner. And claiming rights to your post-employment inventions? Crazy. They'd have to fight your next employer, who has a MUCH better claim. So feel free to sign - it's a bogus agreement.
