Even if it were true that societies today are more complex, why is that inherently more special than a time in the past when life was simple? How come so many people today long for a much simpler life, like in the past, as if the past was special? The point is, special is highly subjective and you really should be doubting your own notions of it.

In any case, I think that the original commenter really referred to how there’s nothing so drastically different about the experience of being human in the present and in the past.
