Funny. I work in aviation and particularly in innovation. And progress is actually (and thankfully) slow!!! But this has more to do with regulation about safety management (which is a very good thing!), the low profit margins in the industry (making developing new tech very expensive), the lifespan of airframes, etc. and less with standardizations by governments. How many aircraft manufacturers are there? Primarily two: Boeing and Airbus, both subsidized…Do you claim there is no competition in the aviation and automotive industries?
Those are two industries locked down extremely heavily with standards and regulations. Both are extremely competitive.
