This is a lecture given by Michael Crichton at Caltech titled, "Aliens Cause Global Warming". I just finished reading the incredible piece. He calls SETI a religion and moves on to other "scientific" material. The following stood out:
"This fascination with computer models is something I understand very well. Richard Feynmann called it a disease. I fear he is right."
I think of Feynman as the most lively and diligent scientist of the 20th century and it's nice to know what his opinion was about this "science".
The whole lecture by Crichton is worth reading.
