This has been true for a while with digital art, photoshop, etc. Over time, people's BS detectors get tuned. I mean, scrolling by quickly in a feed, yeah, you might miss if an image is "real" or not, but if you see a series of photos side by side of the same subject (like an OF model), you'll figure it out.

Also, using AI will not allow you to better express yourself. To use an analogy, it will not put your self-expression into any better focus, but just apply one of the stock IG filters to it.
