Ironically, when I saw the headline I thought to myself "what's with this conspiracy with people constantly trying to push this narrative that people should reject morning stuff", and then the top comment is complaining about a "conspiracy to make people wake up early".

From an evolutionary perspective I guess you can try to argue that in the past there was some benefit to some people being on a shifted schedule so they can stay awake to keep watch at night, but I feel like overwhelmingly throughout human history people mostly just naturally woke up when the sun rose and anyone that stayed at camp sleeping in, not helping with duties, was very looked down upon by the rest of the group.
