Thank you for clarifying. The crux is, I guess, that you are making assumptions (valid at that) based on history, whereas I believe that the start-up rush is unprecedented and cannot be easily compared with anything that has happened so far. The author's analogy of land rush was, in my opinion, close, but the fact is, nobody knows. Another fact that I would like to address is that just like the oil rig you mentioned has tangible value, (engineering, ore and manufacturing), so does software (engineering, data and massive outreach), so to quote Winston Churchill, "This is not the beginning of the end. It is the end (or not even that) of the beginning."
