One massive difference is how much easier it is to learn and practice these days.
I'd wager it's also going to be less stigmatised as 'nerdy' or 'uncool'.
It's neat when your kids get excited about something - especially as full and rich as chess.
This is good, but it's easy come easy go. I'd caution against her overtraining or setting the bar too high. It takes time, learning chess teaches many good habits, pacing, and patience. It's also discouraging like nothing else when you hit a plateau. Never let her think she's not smart enough to overcome it or that it says something negative about her. Forcing yourself through it burns you out.
In my case, for something like four years I genuinely couldn't look at a chessboard without feeling stressed, defeated, stupid, and angry with myself. It took time to be fun again.
Dunno if it helps, but I both play and taught a bunch of people. If you have questions or an opponent, I'm here and or lichess.
