as usual these things are presented as new and revolutionary but aren't actually.

the specific process and implemention however are usually newer or slightly different from before.

this is our sensationalistic based society - any iterative progress, or sometimes even copy, is explained as a revolution.

now show me a 737 using 40% less fuel - guess what - that wont happen - however, perhaps we'll get a slightly better process to create aircraft skins. keep in mind you cant re-sand a fuselage every week, it needs to work reliably with no maintenance.
