I probably say this is every thread about this, but I think people are mad because they thought there was a larger narrative at work wherein he was working his way up an imagined tech tree. That was never the case though, and you can’t go much farther than he has by yourself. I guess it speaks to the quality of history education that people don’t understand it takes a village and specialization to make things better than a mud hut. Or maybe doomsday prepper culture has infected everything and people think they can all be lone wolf heroes (but have never actually tried to make things).
