A few of my thoughts
Here are some of my thoughts of blackjack in casinos in the next 5-10 years:
Blackjack will live on, but beatable conditions will be far and few.
CSMs will dominate the percentage of blackjack tables.
Double and six deck shoes will be replaced by eight deck games that aren't worth trying to beat.
Counters from this era will eventually retire and the next generation of blackjack players won't be able to implement strategies and ideas written in classic books since those games will hardly exist.
Backcounters will be spotted immediately since eight decks take a long time to deal out, and the window of opportunity is small.
The beatable games may still be around, but only in the high limit room where scrutiny is high, and the table minimum will be too much for most.
