(btw great comments above gents, voted them all up) We crave efficiency, but always end up in local optima based on resource allocation limitations. Great business opportunities are creatively observed by sharp minds and unleashed by relentless entrepreneurship. There are social forces pushing towards lower cost, ease of access, higher functionality and always entertainment!
