Interestingness is objective enough to argue about. (Interestingly enough, that is the very paper that eventually led me to apply for Visiting Fellowship at SIAI.) I think that the phenomena you listed are not nearly as interesting as macroeconomics, nuclear bombs, genetically engineered corn, supercomputers, or the singularity.

Edit: I misunderstood the point of your argument. Going back to responding to your actual argument...

I still contend that we live in a very improbably interesting time, i.e. on the verge of a technological singularity. Nonetheless this is contentious and I haven't done the back of the envelope probability calculations yet. I will try to unpack my intuitions via arithmetic after I have slept. Unfortunately we run into anthropic reference class problems and reality fluid ambiguities where it'll be hard to justify my intuitions. That happens a lot.
