I have no interest in your presenting your unwillingness to do basic research as if it was a valid form of skepticism.
Whether or not you believe me, everyone else just went ahead and took a quick look, and learned something.
Frankly, I would be happier, given your seeming inability to be a part of this conversation in a polite way, yet also your seeming unwillingness to depart this conversation even after it was requested, that you actually believe I'm wrong, and go around "calling people on this," so that everyone has early warning just how much you actually know about this field, instead of having to wait to listen to you speak.
"Shannon was a much better chess player than any program available in 1949."
On a technicality, this is correct: he started his work on December 29, and it wasn't until five days later, January 2 of 1950, that it was able to beat him.
All the same, you have no idea what you're talking about, and are asserting your beliefs as fact.
The correct way to handle "that doesn't sound right" is a search engine, not putting your hands on your hips and telling someone they're wrong in public.
I call "citation needed", and needed quite badly: Shannon was a much better chess player than any program available in 1949.
