Hitting the ball back.

How do you get better at ping pong?

You can hire a really good coach. Yes.

But that isn't enough.

You need someone to hit the ball back to you.

Again, and again, and again.

If you find someone who is willing to do that, you would get better.

More than anything else, I think this is what AI is most helpful for. It can hit the ball back to you so that you can hit it again. Again and again. At your schedule.

All it has to do is hit it in a way that you can hit it back.
