Yeah I am using the paid version of midjourney, you got a zar300 per month version and the one above is zar600.
I do use it for merchs, and constantly monetize it so it makes sense to use pro version for me.
You could always try it for free and see if you like it. You will find many other software online like nightcafe studio, wonderapp, stablediffusion and many more!
I also find it fascinating, and for me just a great way to express my abundant creativity.
Thanks, man! I will check it out. It looks really fascinating and scary at the same time. Our minds are capable of so much, with the power of AI it is just infinitely crazy. I do not know if you are into stuff like that or if you even have the time, but there is a YouTube video about how crazy these things can get. Nexpo, the YouTuber, covered a case. I'll link it below if you have time.
