I think your best bet would be to ask the room owners that question. As for myself, in 2005 I took a break from pool and stayed out of the poolhall until this past fall. Since back I have noticed a decline in the number of people playing, compared to almost five years ago, and especially during the daytime.
I certainly don't believe that pool will ever become extinct though. As a matter-of-fact I've read that poolroom business was quite high during the great depression, albeit there was certainly less money to spend.
