Abbadon,
What i mean is only skin deep, that's as far as i can go.
I am under the impression that the 80 years old man ended his investigations where he started, and gave up.
Seem like originally he proposed to explain the origin of life my scientific method, but his tools failed him.
Did he tried NERSC? (IBM with 6,080 processors for running scientific applications).
Anyway it is like the internal combustion engine equiped with four wheel, steering wheel, radar and autopilot trying to figure out by herself where she came from.
No 'regret' class
