Cornell University researchers allegedly “created a machine that can build copies of itself.”
All that is left is to add a factory to the Cornell device so it can produce for itself the molecubes that humans keep building and feeding them.
Any evolving system of RNAs would quickly include almost exclusively RNAs that performed no biologically useful actions.
A reader must ask if an RNA molecule could possibly govern chemical reactions, suppress free-riders, support co-operators, and act in its own self-interest.
Professor Hansma maintains that sets of integrated reactions could have been directed by natural selection to gradually evolve into an autonomous cell.
