And this improved technology was an inevitable, foregone conclusion?
People make arguments like this as if it was some passive thing, as opposed to thousands if not millions of conscious decisions to improve turbines, airframes, and myriad other technologies, then actually implement them in real aircraft, then acquire and deploy a commercial fleet.
People made these decisions because they were incentivized to trade time and money today for material improvements tomorrow. Why do you think that might have been?
Hint: think about industries where there isn't much competition. Do we see similar improvements there, usually?
