> Stable Diffusion isn't going to destroy art since art is fundamentally a human endeavor. But many of the creative professions commonly called "[something] artist", whose day-to-day work consists of drawing pictures to illustrate a point, making things "look good" etc. are absolutely going to be wiped out. Logo designs, cover illustrations for books and music albums, pictures for marketing releases and so on.
Logo designs are absolutely critical for companies that want a consistent marketing, advertising and branding (so, like, all of them). AI is also notoriously bad at making legible text. Saying Stable Diffusion can design company logos is the marketing equivalent of saying you can use ChatGPT to design your company's backend database schema; only true in the most reductive and simple of cases.
I would look into the current process for cover designs for books and albums. Either the commissioner is requesting a drawn illustration in the artists' style specifically, in which case AI doesn't help; or, if they're requesting generic cover art, the process is already very optimized. Illustrators heavily use stock images, do postprocessing in Photoshop, put text on as appropriate, and call it a day. These illustrators will start using SD as part of their workflow; if anyone is a potential casualty of SD, it's going to be Gettyimages and their ilk.
Again, this is buying way too much into the hype, and is a typical perspective of someone with little direct experience in paid artwork. The comparison to blockchain is apt; many people were talking about how blockchain would solve problems with "supply chain", "voter fraud", etc because they thought about the problem for 10 minutes and it seemed good. Of course, none of those people had ever worked in those areas, but it didn't stop them from talking about how disruptive blockchain would be!
edit: To put it in perspective, Tropicana's infamous rebrand cost them $55 million[0]. That's how much of an investment companies put into branding exercises. You really think they're going to be satisfied with a "good enough" AI logo at that scale?
