perhaps the cheerleaders who pout about our 'slow' progress are doing us a service by trying to motivate us. but i also see them as pesky and annoying.
while some measure of r&d benefits from the feedback loop of failure to industrialize or failures learned from in the industrialization of extant technologies, ------the reality is that basic r&d needs to be done. much much more of it.
pushing relentlessly for industrialization at a stage in time where the technology IS NOT YET READY TO SCALE RELATIVE TO OUR EXISTING BASE---------is just foolishness and a waste of money.
BETTER TO SPEND THE MONEY IN R&D, THAN TO WASTE TOO MUCH OF IT ON NON-SCALEABLE SYSTEMS.
