How could an article on the AI aesthetic not mention the curiously anatomical company logos?
On a more serious note, I like the tiny icon trend as depicted in the article. Those little icons next to menu text are pretty ornamental, and don't need to be as big as they usually are.
The nice thing about web and electron apps is you generally get zoom for free. I like the icons as they just kind of work better for my brain.
The issue with the icons is not the diameter but their stroke thickness — it should be the same as the letters.
