Blender's UI has improved tremendously over the years, but I wouldn't call it one of the cleanest UI in software. It still has, for better or worse, quite idiosyncratic UI patterns (e.g. the panel juggling) and the underlying logic of e.g. objects, meshes, textures, materials, world, camera and renderer lining up is not very discoverable.

I'm highly sceptical anyone could learn the Blender UI just by opening it and clicking around.

Specific features are hard to find from tutorials. LLMs don't replace tutorials, they augment documentation and stack exchange and such.

Visually clean, sure. Intuitive? Hmm Blender was notorious for having a difficult to follow UI for years. They've improved it a lot over the last 10 years but I still wouldn't say it's easy to use. Way more stuff requires a tutorial than one would hope.

Honestly the fact that you're doubting the usefulness of AI for this makes me suspect you haven't really used Blender in anger.

I have used blender plenty, I don't think it's mega intuitive, but it's not "I need something else to do the thinking for me" level hard.

Nobody said "need". Obviously you can look up all the tutorials if you want to do it slowly.

Think about it like fancy search. You can manually look through a document ("I don't need something else to do the searching for me"), or you can just use Ctrl+F.

Yeah, or you can spin up a few GPU clusters, upload your entire document, and ask it.

Blender has built-in search. That's not what this is.
