Unless you're expecting an LLM to have access to literally all information on earth at all times I find it really hard to care about this particular type of complaint.
My calculator can't conjugate German verbs. That's fine IMO. It's just a tool
Yes but a tool for what? When asked a question individuals that don't already have detailed knowledge of a topic are left with no way to tell if the AI generated response is complete bullshit, uselessly superficial, or detailed and on point. The only way to be sure is to then go do the standard search engine grovel looking for authoritative sources.
