Certain games may die, or become unplayable. But it all depends on your ability to adapt, or to play worse conditions. Would you be willing to back-count 6 deckers with 2 decks cut off? Most here wouldn't, but a generation ago most wouldn't play shoes, or any games other than S17 DAS DOA.
Personally, if I saw the conditions decline, I'd still be in there grinding away, or finding new edges to shoot. Hell, casino bonus whoring is the greatest advantage play in the history of the world. It's a good time to be alive, and I expect it to get better. If it doesn't, I'll pull my money out and buy real estate.
