| Quote | I have little doubt Lord Kelvin adjusted his original 20 million year old estimate in 1897 the year after Becquerel discovered radioactivity. However, 30 years before that he was arguing against Darwin's suggestion that the earth must be older.

Kelvin didn't wait for radioactivity to adjust his estimate. He made continuous adjustments.
And he was correct to demand a mechanism that would allow the sun to be older.
As for Penrose, he assumes that brains a re digital, when it is obvious to everyone wo studies neurons in detail that there is a significant analog component. Namely firing rate.
It is quite difficult to do analog computing in silicon. The cost gets astronomical when you try to emulate analog behavior with digital circuits. In another discussion I referred people to the Brains In Silicon project at Stanford.
