Many casinos don't use auto-shufflers on all games, especially on higher limit games, because gamblers generally don't trust them. This applies to all casinos on the Strip that I'm aware of. Re: it being hard to figure out on 6-8 decks, the scenario presented was that his mind is a supercomputer with perfect memory and he has perfect vision. So he could very easily determine the exact order of an unlimited number of cards by watching the shuffle and knowing the starting order of the cards (that being said, you can walk into any high end casino on the strip and play up to 6 blackjack spots at $10,000 each on a hand-shuffled, double deck game - MGM, Aria, Bellagio, Mandalay Bay, Caesars Palace, The Mirage, etc). You're thinking in terms of human constraints; that's not what this hypothetical was about.
