Yeah, but a child does one-shot learning much better. Just tell it to find the black rectangles and it will draw boxes around the transistors of a PCB, no extra training required.
In either case, your assertion that one _understands_, and the other doesn't, seems like motivated reasoning, rather than identifying something fundamental about the situation.
But at least with a child I can quickly teach it to follow simple orders, while this AI requires hours of annotating + training, even for simple changes in instructions.
The other problem with LLMs today, is that they don't persist any learning they do from their everyday inference and interaction with users; at least not in real-time. So it makes them harder to instruct in a useful way.
But it seems inevitable that both their pre-training, and ability to seamlessly continue to learn afterward, should improve over the coming years.
