Most Americans know who Albert Einstein was, but comparatively very few people know who Neil deGrasse Tyson is. They know who Kim Kardashian is, though! In the present in the United States, entertainment and lowest-common-denominator appeal are revered and expertise has less impact than demagoguery. When people stop admiring intelligence, they stop working to attain it. That's where we are now. The United States has a lot to learn from other older, more mature cultures, and I hope we can wisen up soon.
