How do you know if an artist drew it for you versus an AI? I think social proof and long term observation of artists help.

Approps of nothing, I think art is worth your while to make an investment of effort. I found Drink and Draw and made acquaintance of another maker from a local makerspace(not mine) and an artist. I wasn't technically adept but I want space to learn how to draw and they treated beginner(or at lease those three) with good vibes even though I was a clear beginner.
