It was joke ...
Now there is a lot of contradicting material on it ... so there has to be a lot of disinfo between all the good and serious stuff.
Problem with the world wide web today is that we have too many self proclaimed experts. It's true, we are a lot smarter
nowadays since we can learn more and more. But we should not pretend that we know it all now.
We're fed a lot of stuff via several channels ... all we can do is a simple smell test (validation and verification of presented data).
But we should realize most of us are still laymen on the vast number of topics fired at us daily ... so smell twice before eating
what's fed to us (until we learn how to feed ourselves !).
