Running high-powered AI locally seems like a pretty good use case to me. Cloud-based AI, like OpenAI sells, is expensive and provides inadequate privacy. I want a truly personal computer, not a dumb client.
If the chance of hallucination could be statistically guaranteed to be near 0, then it would have many more use cases, imo... but why would I have it summarize a pdf or write some complex code or something if I have to always double check everything for accuracy?
A calculator has no use case if it might be wrong.
