Bashing Wolfram's personality is an easy way to get attention on the internet. Most people who do so did not study with Feynman, build software that altered the way scientists are able to use mathematics, or build and run a successful bootstrapped technology company for three decades. Or write a book explaining a sophisticated original idea.
My hunch is that Wolfram's work shares some sort of fundamental mathematical relationship to current advances in machine learning using neural networks. Independent of my hunch, I don't deny that Wolfram could be wrong. But I believe there is a non-trivial possibility that he is on to something important even though it may not be apparent for many years. This was the case with Boole.
There are plenty of excuses not to read his book and most people don't. Not reading doesn't prevent talking about it and joining when people are bashing Wolfram.
Good luck.
