It&#x27;s possible that you did not understand the original article. Or perhaps you did not read it. When you write:<p>&quot;Each technology lowered the cost of starting and running businesses&quot;<p>No, not in those industries. When an industry consolidates, the cost of the starting a new business in that industry skyrockets. Eventually it becomes impossible to start a new company in that industry. That clearly happened for trains and automobiles, microprocessors, and certainly now for Internet companies.<p>This is a pat re-statement of a tired cliche:<p>&quot;They all spawned brand new ecosystems that created entirely new opportunities for entrepreneurs to create wealth.&quot;<p>There will probably be economic growth in the future. I mentioned one obvious industry that is still forming: genetic engineering. That doesn&#x27;t change the fact that the gold rush has come to an end for Internet startups.<p>Here you are changing the subject:<p>&quot;The train even unified some nation states that didn&#x27;t exist.&quot;<p>I come back to my original diagnosis: Your comment sounds like pure denial. You don&#x27;t want to face a painful truth, so you create a rationalization.
