It is often said an average worker now makes less money than in 1970 (example of going backwards) and it seems the working hours are longer (example of going backwards).
These are encumbrances in motion. We are talking about evolved economic markets demanding more of a country and thereby creating globalization in order to tackle world debt and economical instabilities, especially now in richer countries such as America with the decline of the dollar.
Science may have a limit, but matter may not. Imagine that science does stop evolving and reaches a limit where it cannot manipulate matter any further. This could be for economical, social, political or cultural reasons.
It’s almost impossible and if not totally impossible for science to stop and hence halting the production of matter alongside it. I must however concur with you when you state, with the exclusion of referring to possibility (could), that this is due to economical, social, political or cultural reasons. This IS because of the reasons you’ve mentioned.
It’s in my opinion to think that in postulating science and the possibility of stopping matter through it, as being quite bold. I further believe that it is infinite, science will always evolve, with or without restrictions.
