If we accept that AI is a tool, then then problem is the nature of the tool as it will vary heavily from individual to individual. This partially accounts for the ridiculous differences from self reported accounts of people, who use it on a regular basis.
And then, there is a possibility that my questions are not that unusual and/or are well documented ( quite possible ) so my perception of the usefulness of those answers is skewed.
My recent interaction with o4 was pretty decent on a very new ( by industry standards ) development and while documentation for it exists, it is a swirling vortex of insanity from where I sit. I was actually amazed to see how easily 4o saw some of those discrepancies and listed those to me along with likely pitfalls that may come with it. We will be able to find if that prediction holds v.soon.
What I am saying is that it has its uses.
