I think he's good as long as you can remain critical - he's brings up some good topics but people need to come to their own conclusions. He's pretty anti-SpaceX, but I think some of his criticisms are off there.

I remember one of his arguments was that starship was nothing special because fully-reusable launch vehicles had already been tested - but who cares about that? On the other hand, his criticism of musk's vegas tunnel is fairly spot-on IMO.
