It just has the same cadence and patterns as a lot of the overt slop writing I have read has.

Im happy to consider a second opinion if you think its not AI generated?

The first two sentences, on their own, do have a slight whiff of AI about them, but I would 100% believe were human. But that last one, especially in combination with the first two, absolutely reeks of AI. Making a grandiose-sounding "it's this, not that" style statement is a classic AI thing. Not that humans can't write something of the form "it's this, not that", but the way humans tend to do it feels more organic, and less like it's a failed attempt at presenting a hugely enlightening concluding remark.
