The efficiency and the safety. Modern planes are disgustingly safe to the point that hull loss is almost unheard of. For 50 years the industry has optimized for safety and fuel efficiency. And the modern machines are marvels in that.

True, but still incremental improvements over proven designs - maybe a sign of very strict safety standards making new designs and differentiation more expensive than just the development.

Or more likely, that’s exactly how you make incredibly safe systems.

Not by introducing clean sheet unproven designs but by taking what works and improving any deficiencies over and over again.
