It's also unclear what conversing agents are useful for other than wasting money, energy and water.

It's hard enough to get the same model to be consistent around it's vision let alone multiple of them.

I'm building an EMR and the other day asked Claude what a decent model would look like for capturing wound orders. Then, I took the output, started a new session and asked the new session to critique that model and the response made me want to pull my hair out. It blasted the model from it's former self and suggested making a ton of updates.

I'm sure more scoped tasks would fair better, but it was pretty frustrating.

If I don't see the point of Elixir, or I don't like it, or I simply straight up hate it, why would I go into HN submissions about new Elixir versions and spew my personal opinion that has nothing to do with the topic at hand?

You can just skip commenting unless you have something actually useful to add. Even if it's criticism of the specific thing, but at the very least make it on topic instead of general digressions that just add noise to the conversation.
