Ok Paul, you are right, we are that dumb. After all look at James Watt. He invented a steam engine but didn't stop to think that it would lead to an enormous increase in the use of fossil fuels, and that the increase would lead to global warming. He should of course have thought out all the consequences and gone to work on alternative energy sources instead.
