On a slightly more positive note...
I followed this article at the weekend to create a custom chatbot and downloaded 200+ Oracle Docs NS User Guides and fed them to it.

It 'aint fast, it's less clever and more "cleva" but it was a fun experiment and I could see how feeding company docs in to it could save a business time particularly if you work on support.
