I've built some AI-powered software before, and the issue for a lot of the consumer-facing tools such as this one is that a few incorrect results voids the value of the whole system. I think you'd probably need >95% accuracy for the benefits to outweigh the cost, and looking at the comments here it's clear that that bar has not been cleared.
To put it simply: If you can't be sure that the results are accurate, how can you default to this search system?
