This is a neat site, honestly this reason alone is reason enough for me to be glad that Grok exists, even though I don't really use it and I have a ton of beef with libertarianism.

Just like how people complain about Airbnbs looking the same all over the world now, it's a real risk that thought itself might similarly homogenize. Unless you really trust a particular model to deliver The Truth, you should want to have many popular models that represent a variety of beliefs.
