This is a great sample of "truth [being] stranger than fiction". Can verify many of the examples from memory. Most memorable: the Encarta Encyclopedia CD-ROM illustration/splash screen.
This website has existed for a while. I know some of the examples to be real. When it comes to names, I think they've explained the origin in some cases. There's a log of the changes they've made over time.
Professional designer and commercial artist here: all looks legit. The names are either in very common parlance (eg vaporwave, Corporate Memphis) or slightly less common but still used (eg Zen-X) and the images I saw I either recognized, or they seemed genuine. Even if they were AI-generated, I think "inspo/mood board" type applications like this are probably one of their only genuinely useful professional applications right now. Grouping images by some conceptual underpinning communicates that concept far easier and more effectively than words ever could: and as long as those images convey that idea, it doesn't matter if that one little inanimate objects in a tiny part of the frame is inexplicably made of elbow skin or all the chairs in the image have an odd number of legs.
