But surely there are many gifted ET contributors who work in it - because there are little other alternatives, not-withstanding Chris Cook perhaps. I have attempted to grasp the corollaries of his construct, but I'm afraid I'm out of my wits on that... Nor have I an idea whether he has addressed the sustainability of his model at ET or elsewhere before, but I would be interested to read it.

The economics of today have developed, because they work. It seems evolution to me, in that regard. It happens, because there is a time-window for it. One day, the brick wall will come, but that's no worry for the species of today. Evolution has no long term strategy. It's opportune, it just is - and apparently so is economics.
