I think it's the same. The fish is always there, 10 years ago and recently. The pro wannabe (fish who calls other fish) is also always there. The reg is always there too.
The problem is who are we? No one wants to be called fish. So, we are all pro wannabe.
In terms of more people studying this game, I don't think it's matter. Yeah, many would be tighter on the pre-flop but fish is fish, and reg is reg (Also pro wanna be is pro wanna be).
So, pro wanna be would think it's tougher, reg would think it's the same, and fish would think it's a scam.
Just my two cents, CMIIW.
