Well, it's democratized cheating, so the playing field is still level. I think people would just adapt.
Either that or casinos would change their games.
Anyway, you can already do card counting via computer pretty easily at a casino if you think about it--I'm pretty sure they don't care enough to stop you as long as you aren't obvious and you aren't robbing them.
Oh, they care. If they have any suspicion that you're counting they'll just politely ask you to leave. Casinos are private property and they have the right to kick/ban anyone they want for any reason. Call it unfair, whatever.
And read up on the history of the early card counters and their shoe computers. It's a colorful story.
