Absolutely agree. But, actually, that is not TED who is getting worse, just some of us are getting wiser. I remember these times when I was myself seduced with every other motivational and (pseudo)science speech. Now, working with very serious things, I am seeing total bullshit around every other corner, mountains of life-threatening bullshit in those areas which seemed untouchable great science to me 10 years ago.

I even do not bother to watch and read TED-like sources nowadays (unless they are seriously threatening my field).
