Tech has changed the game for the worse. Been watching the main events for decades. Sure athletes have better medical care now and training regimenes, but the tech has taken away parts of the game that were very fun to watch. Aces aren't. They used to be more special. Sure, the diehard is going to think today's game is great, just like the diehard golf fan who goes out and buys  what he sees his favorite guy using. Tennis will continue in its lower-tiered status as long as tech rules it.
