Realistically everything in this hypothetical conversation will be things that “everyone” knows. Unless you’re discussing confidential info about EVs, everything is by definition public knowledge and probably even common knowledge. Most conversations are about opinions rather than facts.

Is the guy who comments about EVs having all their torque available from a standstill also adding nothing to the conversation? What about the guy who mentions the environmental friendliness? Or the one who mentions the environmental costs of lithium mining? Who is really adding to the conversation here?

> In this conversation, we know there are downsides to cloud-based voice recognition. Telling someone who built it that it’s not for you, doesn’t add any value.

And yet it’s the top comment and the top reply provides info about a platform that doesn’t have the same drawback. I think this is pretty clearly value added.
