We evolved visual and hand dexterity for considerably more than two millions years (more like hundreds of millions, I don't care to go find out when hands first evolved but the neural crest was 550 million years ago), and we need many, many more than "only few examples" to be able to draw hands, let alone a sentence. This is something you could only possibly say if you have never tried to draw a realistic hand. There is a reason that long before AI image generation was publicly talked about, many artists joked all the time about how they could draw everything except hands correctly. Hands are particularly difficult to draw. If anything, it is genuinely interesting and maybe worthy of research as to why hands are so hard for us to draw and why they are so hard for these DL networks to draw, and if the reasons are related.
