I can't speak for the future. I have no crystal ball.

I don't think anybody has that crystal ball but the president.

I'm not in the business of reading tea leaves. I don't have a crystal ball.

You can't gaze in the crystal ball and see the future. What the Internet is going to be in the future is what society makes it.

I bought a crystal ball, and I wanted to use it, but I didn't know how, and I wouldn't use it until I developed a technique to use it that was truthful.

He who lives by the crystal ball will eat shattered glass.
