I don't really care where futurists keep their heads, but they, including Hoel, use them intermittently, superficially and in a slipshod manner. They don't do their homework.

I very much doubt that Hoel has properly thought through in detail what it would take to operate a permanent colony on Mars and what would have to happen to set one up. If he has, he has not troubled to write down his thoughts.

As an example of what I'm talking about, Brian Potter, on his blog "Construction Physics", has delved into the detail and explained some of the mass of physical, economic, informational, institutional, organisational, and cultural factors that result in the building construction industry and construction costs being what they are.[1]

I have never seen its like from any futurist.
