AI, ChatGPT, Grok and the Wizard of OZ

Okay, maybe I've got this all wrong.

Is AI a search engine that spits out what it finds on a given subject of already existing information that is currently stored on existing platforms across the internet (therefor it's as good as the information it finds, the old "garbage in, garbage out" problem)

or does it analyze & synthesize variables to form a NEW composite picture that provides unique insight into the requested subject?

For instance, "What effect would finding uranium on Navajo tribal land have on code talkers finding affordable housing in Farmington NM? Is there sufficient water to handle the increase and how much could I get for rents?"

AI should be able to handle those kinds of questions. Otherwise, you're just using search engines that tell you general information, which have been around for decades and can be reached without using Chat GPT or Grok and any other engine.

Or am I wrong? Does AI do that already?
