No, I think it's a bit ridiculous to assume that everyone would be microdosing or that it provides such a massive competitive edge such that the drawbacks of microdosing are outweighed.
Too much personal introspection and autobiographical thinking. Tangential thoughts not relevant to the task at hand. Lack of linear focus. That kind of thing.
I bet people are just a little more weird microdosing psychedelics. Like, come on if it impacts your ability to create novel things, then you are going to create novel conversation topics and some of those are going to be fucking weird. I love acid for personal development but I am not sure if I could handle this reality.
