       | 
       | Ideas are an abstract thing. To realise an idea, one needs
       | material resources.
       | 
       | The problem has nothing to do with either finite material
       | resources or ideas. The problem is what those material resources
       | get converted into. What we do is we transform one type of
       | material into another during any activity. How we can limit
       | ourselves to not transforming these useable material into
       | unuseable material is what is the challenge for growth. We should
       | only be promoting those ideas that have a better opportunity to
       | transform one usable material resource into another usable
       | resource without taking much time and without harming the
       | ecology.

       | Well you really only need a small number of very talented brains.
       | And continuing to grow the global population is probably not the
       | most efficient way of getting them.

             | good, factual article illustrating my general point:
             | https://www.nature.com/articles/537466a
             | 
             | Reading between the lines, I think your view is that the
             | valuable contributors (the extreme outliers) will find a
             | way to contribute regardless of background. I think that's
             | true, to some extent, but less common than we give it
             | credit for. I also think that ignores the majority of
             | scientists who are not outliers but make important
             | discoveries just as a matter of course. Discoveries that
             | may inform future breakthroughs.
             | 
             | Anyway, the truth is certainly somewhere in the middle. By
             | growing the population of people who might make
             | contributions (one way or another), we will increase the
             | rate of contributions. I just think it's best from a moral,
             | social, and ecological perspective to make the most of the
             | minds we already have.

       | This is utter nonsense. Progress never stalls (except if we
       | happen to extinguish ourselves). It did not stall the last
       | 10,000+ years despite very low population numbers except in the
       | last 300 years. Of course, it might go a bit slower or faster
       | depending on demographics.
       | 
       | But that is not important. We already have all the technology
       | that could make a decent life possible for everyone on this
       | planet. It's more a matter of applying what we already know. Of
       | course, better technology might help with that -- as could a
       | decrease in population. But if we do not get better in applying
       | our knowledge for the benefit of all, we are doomed.

       | So then the question then becomes, does the real rate of return
       | for any particular company or the stock market as a whole assume
       | that a potential future exists in which that real rate of return
       | is actually possible to exist?
       | 
       | Let's assume, in a model as simplistic as possible, that there is
       | one stock (or market) that represents all of the world's
       | companies that has a real rate of return of 2.5 percent per annum
       | that is compounded once per year. As a sum total of world wide
       | growth this would seem rather modest. The worldwide initial
       | capital we'll assume is $100.
       | 
       | So the growth rate is given by A = P(100 + r/n)^(nt) which would
       | be in our case (for an investment of 100 dollars) -
       | 
       | 100x(1.025^10) = $128.
       | 
       | So for the real capital stock of $100 to increase to a real
       | capital stock of $128 some combination of things must happen -
       | the amount of capital stock in terms of raw resources must
       | increase in real terms and the amount of technology must increase
       | in order to make the use of these inputs more efficiently.
       | 
       | If technology remains constant then there must be an increase of
       | 28% over ten years of capital. If capital remains constant then
       | technology must make the current use of capital 28% more
       | efficient.
       | 
       | Compound return over time is concerning in the long run, and hand
       | waving it away is either ignorant at best or disingenuous at
       | worst.
       | 
       | And capitalism is still the best distribution system we have come
       | up with. Most of the world is working with a single overall
       | social model, because it has been so successful, and we don't
       | have a backup that's been shown to work in practice. My concern
       | isn't in favor of Das Kapital or Marxism - who owns the product
       | of labor and historicism over labor rights isn't as concerning as
       | compound interest over all.
       | 
       | Most economists I've worked with don't seem to think that this is
       | a problem or that technology will magically free market a utopian
       | future of plenty for all. This is an article of faith.

           | 
           | There are a few pretty obvious reasons why this is true.
           | First, "currently having resources" is not a good indicator

           | requiring action by a government (or some equivalently
           | collective entity) to properly account for externalities.
           | Third, mismatched negotiating power (because employees _must_
           | agree to some employment or else starve) mean that even those
           | actually party to any given agreement might not be maximizing
           | their own resource allocation by doing so. And fourth (not
           | finally, but finally off the top of my head), there are
           | problems of diversification in the face of uncertainty -
           | resource-havers can take maximum-expected-value actions even
           | when they have low probability of payoff (e.g., risky

           | variance; non-resource-havers must settle for lower-expected-
           | value but lower-variance options, which limits their success

             | 
             | That's simply not true that this is "very well known." And

             | Forceful power, i.e. "power," is just not comparable to the
             | "power" one gets by voluntarily trading with others.
             | 
             | It's silly to say your non sequitur is "well known" by
