Aww I feel you.

Honestly I don't think you should feel too hard on yourself — AI is becoming increasingly difficult to tell apart from real art, and majority of the blame should be on AI """artists""" who know what they're doing yet continue anyway because they want to exploit clicks/views/whatever. I know I've accidentally shared AI art before, esp. on twitter, so I'm not any different from you, but once I learn it's AI I immediately take it back. I am always,
always open to being called out that what I shared is AI; I love sharing art because real artists deserve recognition. Unfortunately, a lot of people will try to exploit people's excitement by passing up AI art as real art. It's horrible and it's disappointing.
I will never believe that AI art is real art. Art takes time and talent and skill, something you hone for long; if someone else does this hard work for you then it's not really you who learned, no? The AI is learning more and more when it should be you who is learning. AI may be able to replicate art, but it will never replicate the happiness I feel making my own piece of work from my own two hands, with my own skill that I honed.
Anyway yeah, my two cents. Don't worry about rambling!! I know you mean good.

What we can do now is to keep on spreading awareness and support real artists.

I'm hoping everyone learns from this trend and comes out as better people.
