I agree that LLMs have opened modalities we didn't have before, namely:

- natural language input

- ability to synthesize information across multiple sources

- conversational interface for iterative interaction

That feels magical and similar to Star Trek.

However they fundamentally require trustworthy search to ground their knowledge in, in order to suppress hallucination and provide accurate access to real time information. I never saw someone having to double-check computer's response in Star Trek. It is a fundamental requirement of such interface. So currently we need both model and search to be great, and finding great search is increasingly hard (I know as we are trying to build one).

(fwiw, the 'actual' Star Trek computer one day might emerge through a different tech path than LLMs + search, but that's a different topic. but for now any attempt of an end-to-end system with hat ambition will have search as its weakest link)
