Another point on which I would voice an opinion -
if the limits of man's ability was only what Man has done before - we wouldn't have left the caves... :-)
And we wouldn't have Beethoven's ninth symphony, or Ivanchuk's Qxg7!!
Not to mention chess engines...
Man is all about doing what has NOT been done before.
The opposite view is known as CONSERVATISM.
Not that there's anything wrong with it - and it's a benchmark all too often - but thankfully it has its EXCEPTIONS.
And these exceptions are what matters.
<Pritesh36> +1 and thanks for your kind words. What you write about his kind is spot on!
I like very much the attitude of both NMs from the end of page 2... :-) - as well as <PMG8>'s (page 2), and the attitudes and messages of <Inexorable88>, <SDRealm>, <IPress12> (nothing like FACTS IN YOUR FACE!>, <BlunderLots>, one sentence in the post of <ChessOath>, and all of his next post, (page 3).
