Also your dunning-kruger is showing.
Simple answer to complex problems, outside science and engineering, are almost always wrong. The world is complex and naive answers are not sufficient, even if the subjectively make sense to you.
The guy is part of the establishment you're talking about: reason dominated the humankind for a few centuries and we are just now managing to converge to something better, while still being immersed in a reason-based society that is crumbling, leaving big voids filled by any kind of ideological scum because the post-reason is not here yet. But anyway, your conspiracy of philosophers against engineers has no root in reality and it's just fear of the complexity of the world.
