After the Alzheimer's research scandal, the Surgisphere study published in The Lancet, and countless meta studies showing that across nearly all disciplines statistical errors significant enough to negate results are present in at least half of published research, and after my own experience with doctors and specialists, I conclude that Grok and most of the search engines' free AIs are pretty competitive.
How many doctors have you seen cited by media or on social media that are totally full of crap? How many doctors have told you things that demonstrably false?
I have used AIs for resistance training regimens and advice on peptides. I take it a seriously as I take a good poster on this forum and more seriously than about half of my doctors. It is just much more convenient to ask Grok than it is to search the now almost worthless engines or ask a question here.
An AI will typically give it's "reasoning" and provide links to its sources which absolutely must be verified when it's important to you.
25 years ago, people used to say, "What, did you read that on the internet? Lol, that could have been some guy in his mom's basement!" As if believing everything you read in your favorite paper is a safer bet. There is no end to your search for the truth, but AI is about the best beginning I have ever found.
The drawback comes when you, yourself, are incapable of parsing the information at some particular level of complexity. This happens to all of us at some point, but if your bar is too low, then maybe it's best not to read too deeply. In that case, I'm not sure trusting an AI is worse than trusting a GP or renowned YouTube doc or whomever Oprah trusts. And it's only getting better.
