Not really. The canonical example of tech that does benefit from the network effect is the telephone. The more people on the telephone network, the more useful it becomes. A phone network that silently replaces each node with LLM agents would soon become apparent as when you catch up with the people you thought you were calling in the flesh, discrepancies will start to emerge.
But Reddit (and HN for that matter) tries to hide the existence of people. While I assume you are human, I don't really know. I don't know your name. I don't know what you look like. I don't know where you live. I know nothing. And, frankly, I don't need to because you are not part of the experience. That you are (probably) human is just an implementation detail. Whether you are human or an LLM is completely immaterial. What human participation there might be when using a forum is done so in solitude. It is not a social experience.
"Swimming isn't swimming but flying because both involve moving through a fluid".
Ok.
Ok. Sure. You can take that position, but it is not clear how you think that fits in the context?
Technically possible, but practically LLMs do not actually outperform domain experts to this date.
