>>3 They've conquered the world of information. Now they are moving on the remaining parts of human civilization.
They get to control Alphabet, while letting each of the lesser companies take all the risks. Instead of shit like Google Self Driving Car, there will just be Self Driving Car, so if it runs over a little kid, Google itself can't be sued.
