On the Internet, concepts are born, live, die and evolve, just like everybody else. Not just concepts, but ways of thinking about things.
Shopping, for example. One of the fundaments of capitalism and modern life. Where the buck passes. By which I mean, old fashioned stores with salesmen and buyers. Thousands depend on them. Thousands more are dependent.
Buyers get pleasure and satisfaction. And things. Salesmen get to feed their families at night. A mutually beneficial situation.
So what kind of havoc will the Internet wreak on this inoffensive arrangement?
First, all the salesmen are killed. Buyers don't need them anymore. But the stores are kept open. The buyers come and all trip off each other, buying things that they see others buying.
Transactions occur. Everybody gets paid.
Eventually, the very concept of a salesman disappears. But it's OK. Everybody lines up at the door. Everybody buys and sells. Everybody gets paid.
