From my personal use of AI, I've found this to be true, but it can be countered. AI is good for number crunching, probably the best thing you can use it for. Rather than spend 10 minutes doing layers of math to come to a conclusion, you can give it the raw info, tell it what you want and let it do the math for you instantly. It's not something I'd stake my life on, but it's a VERY good estimator within a 1-2 point margin for quick estimations and whatnot.

Likewise, if you spend time feeding it information from sources you find yourself, and THEN ask it to analyze it, it's much more accurate than what's being talked about in this post. If you just want it to self-scour, then yeah, it often has holes in it's logic you have to correct. If you feed it a crap ton of info on a subject yourself and then ask it to analyze, the responses are typically much more logical and accurate.

From my own experience, AI is more like a virtual assistant, think like next generation Siri or Alexa, that's good at helping you complete tasks in a shorter amount of time. IE, doing 10+ minutes of math in an instant, or condensing hours or even days of research into a single hour, because all you have to do is feed it the articles and website links and then it will analyze and summarize it for you.

It's not the end all, be all that tech bros like to pretend it is. But it is a useful tool for research, number crunching, etc. It doesn't ELIMINATE effort on your part, but it simplifies things. You can either spend time info dumping from the start and then tell if what you want, or you can ask it a question and gradually refine it to be more accurate through the conversation by correcting logic holes in its answers and making it search itself to fill them.
