Yes, there’s a free lunch

In a physical economy in which scarcity is the fundamental driver, eating lunch means someone else gets less.

But in a society where ideas lead to trust and connection and productivity, where working together is better than working apart, where exchange creates value for both sides…

Then the efficient sharing of ideas is its own free lunch. 

All of us are smarter than any of us, so the value to all goes up when you share.
