If Sergey Brin had told you back in 1998 that he planned to start Google, and to start indexing the web out of his garage, it would not have meant anything. Or if the Wright Brothers had confided in you that they planned to build a workable flying machine back in 1903, they would not have been running any great risk either.
What's valuable is having the vision, and the ability to connect all the little dots, and to see exactly _why_ something is a good proposition. Just hearing that something will be great usually won't help you a lot.
To quote Howard H. Aiken:
"Don't worry about people stealing your ideas. If your ideas are any good, you'll have to ram them down people's throats."
Ask your children if you have any. They will be able to tell you.
