>There is little 'european culture' left ...
That's your opinion, and it strikes me. I don't understand the difference between what you call "fossilized cultural artifacts" and "alive culture and thought". In france, there are a lot of linguistic communities that still talks local tongues, and there are some events in which people reunite themselves in order to perform some folkloric dances (not related to age). Is this a fossilized cultural artifact ?
A lot of the good films I saw the past years were from europe. I really enjoyed the contemporary scandinavian scene recently, you could try to enlarge your vision and watch different things (recommendation [0])
There's a crazy amount of artistic domains, and I can't believe that someone (as you just did) can think of having scanned successfully the whole Europe cultural practices to be allowed to say " european culture is gone".
Music, dance and visual arts are being created everyday : does it constitutes a part of what you call "culture" ?
Concerning the public intellectuals you talk about, well, they were only a diffusion channel for one part of the european culture , and I don't think their death implies the death of culture, but rather the lowering of the signal amplitude perception from USA.
