Thanks for the ping.
Hawkings has been thinking too much and needs to give his brain a rest. It’s getting fried.
Hawking is an industry, we have no clue whose writings are being published, as long as he is alive someone will continue making money publishing what ever they want. We have absolutely no way of knowing if any of the thoughts are his. Sort of like guided writing used by wishful thinking parents if comatose children.
Sort of like using a picture of Billy Maze in the background of a commercial, to make the other guy look more believable.
