Why the negative stigma on "AI" traders/trading software?

So I've been trading for a bit over a year now and wasn't overly successful within the manual trading space despite being somewhat consistent over some time periods. This caused me to have a bit of an open mindset when it came to the idea of implementing systems that could get you in/out of the markets at optimal times. I've noticed throughout my time researching tools of this nature and being a part of different communities where many are very uninterested or even fully against the idea of letting a well-backtested and documented program help them operate within the markets. Leads me to wonder if there's something people are doing wrong on a large scale.. Would any of you be willing to share your experiences with trading software?

I myself have been using a certain tool for a little over a month now and am genuinely happy with what I've seen so far- especially the fact that I don't spend more than 10m a day looking at the charts. I don't want to cross the lines of any kind of promotion and risk getting perma-banned from here but anyone that would like insight into what I'm currently using can shoot me a chat and I'd be happy to share the details of that.
