as the saying goes the trouble with the world is that the fools are cocksure and the intelligent are full of doubt ... my philosophical position ( which i later learned i share with Elon Musk ) is that i am always wrong, but i can strive to be less wrong ... my strategy is to always learn as much as possible and not make any judgements unless absolutely necessary ... but at some point you do have to act / make a judgement ... otherwise your wisdom is just cowardice ...
