I've used Midjourney and...
Message:In the time it takes the bot to process your prompt, you can find multiple other images on Google or your stock site of choice.
You are limited in how many images you can make before you have to pay for the privilege.
I don't pay for beta. Beta means "not done yet." I'm out of free images. It was a moderately amusing couple of hours, but only one image generated was something I found interesting enough to save.
It's very easy to "break" Midjourney by giving it prompts it won't understand or aren't in its database. It's very easy to "break" Midjourney by giving too long a prompt/description. If you use too many words it's going to start putting the text of the prompt into the image.
All that said, AI generated art is here and it's going to be used more and more. All credit should be given to the AI. You give it a prompt, it generates the art. The User then gets a choice to keep the output (and generate variations based on it), or just rerun the prompt. Anyone who puts their own name on a Midjourney generated piece is lying to you.
Metaphoric example - Red had me do the cover for Designing Underworlds (Delvers). He gave me a brief and, after I generated my image he gave notes. He didn't ask for his name to be on the artwork. Red had MORE impact on the product that a user using Midjourney has, because he could give specific notes which I could interpret. To repeat, with Midjourney, the user can basically say "I like this" or "Do it again." It's 99.9% the AI.
