As more people in garages do what could only be done by a major factory a half century ago, we will see all kinds of changes.

In fact, we may see free markets. Not just a market where you are able to buy product A from company A or product B from company A. (Gillette doesn't care if all their customers leave, they will still be buying from Gillette)

It will also be interesting that although you can buy a product from Joe, Frank or Harry, they will all be almost the same and use the same parts to fix it. It will truly be weird. Kinda like, all hoses and spray nozzles all go together.

And, when lots of people own the means of production, then we will both achieve the Marxist dream and the capitalist dream. It will be weird.
