These comments irk me as well. Most of them could add substantive material to the discussion simply by tacking on a few sentences -- you can still start the comment with "Water is wet", but then explain specifically which elements of the story you feel are history repeating itself. And maybe link us to a few of those historical parallels so we can get a sense of how these things tend to evolve over time, or discuss the nuances of the similarities/differences.

Anyways, thank you for calling out low-value discussion. It would be amazing if we could raise the bar a bit.
