Hallucinations don't matter if you check the output before using it, at least as long as it still saves you plenty of time. Can it find 500 issues in a codebase, 470 of which are real? Good. Can it summarize a conversation and find who proposed a certain course of action? Can it go through 170 years of legal precedent and quote relevant cases (better than the existing, conventional search engines, which you would then later use to verify the quoted cases)?
