What's interesting is that the way in which they're childish is actually extremely human. In fact, one of the ways that you're often taught to draw more realistically is to stop thinking of the concepts as icons you're drawing the outlines of, and instead sort of blur your eyes and see things as they are: hues and values. In other words, become a camera or a printer that has no idea what it's capturing or printing other than a grid of values. That is how you achieve realism.
The fact that it has clearly iconified these concepts in its mind and is tracing the outlines of the things it thinks/expects to go where is very human.
Parrots can also sound extremely human, but it’s only mimicry.
How do we know the difference?
Yes, but Parrots don't mimic the stages of learning speech development like children do. They just memorize a phrase.
These SOTA LLMs aren't trying to mimic existing children's drawings, but interestingly they're following somewhat similar progression that human children do as they develop.
They don’t develop. We should stop anthropomorphizing LLMs.
AI labs are improving the ML techniques used to build better models; it’s a big difference.
If you want to know if something is a human or a parrot, you could give it a paint brush and ask it to paint the Mona Lisa.
