I’ve seen some US citizens complain that their country no longer innovates, especially when compared to some of the European countries, Japan or Korea, and their complains are usually exemplified by trains, energy production or education.
However, the US does innovate, and I’d venture to say it’s probably the country with highest level of absolute innovation. The problem is that the US has its own peculiar and very narrow surface area of focus (its perimeter being somehow controlled by politics/corporations). Generally, things that are good for everybody or closely social are outside the area of innovation of the US. But things that benefit the individual and/or produce profit are inside. So, yes, the UV does innovate, and a lot, there’s no doubt about that. It’s only that the distribution of that innovation is very uneven.
Also, for some funny reason, any innovation that makes anything bigger or faster or louder is definitely inside as well! People get excited about and cheer to big stuff in the US!
