You sir, do not know your history, nor the future.
Have you ever noticed the electronic group sets from Mavic and Campagnolo that were there, before Shimano even had 10-speed? I do not want to go into a Shimano-Campa argument, but to state that one is first because they have first commercialized something like electronic shifting (which they haven't), is just picking some elements from a much bigger story to make your argument. SRAM, Campagnolo and Shimano all have shown they were innovative at some moment in time.
Have you checked out the new sub-900 Bianchi Oltre? I guess not. Italian builders CAN make light frames, but they choose sometimes not to do so. Does that make them industry followers? Maybe some companies that DO build light frames are just following...
Same goes for aerodynamics. Have you checked some Cinelli frames from the 80s and 90s? The Bianchi of Berzin in the Vuelta '94? It's not because Bianchi, Colnago, Pinarello and many others do not follow the now-aero-is-the-hype bunch, that they haven't done that already a long time ago (just to conclude that the gains are marginal, and the teams they sponsor just keep winning with or without the 'latest innovation').
Same goes for Campa wheels. Just find wheels that combine excellent bearings, strength, reliability and weight and Campa will always be in the top 3, and they have been there for the last decades. Remember it is easier to reach the top, than to stay there!
Take all the hype with a grain of salt. On every continent, excellent bikes are being made. Some German companies (and forum members) were allready innovating regarding weight a long time ago. To say that one or the other is now an industry leader, considering the criteria regarding 'technical innovation' are vague and industry is very much globalized...
If the criterium is 'desirability', Italy wins hands down.
