That's just patently false. Tons of executives and board members in industry absolutely care. Some are in it just for philanthropic purposes.
The actual logical end point of most of the 'for the good of humanity' folks in the bay area is:
'Only I can be trusted with the money, power, and weapons that I believe will break the world, but I promise it is for the best. No system or power should hold me to account in the event I am wrong or change my mind. Trust me.'
I cannot stand this kind of absolute thinking from the left or right. It’s usually just cope for personal deficiencies.
