Let’s imagine that humanity died out, and new civilzation discovered that human beings used puffer jackets to save body heat.
But they didn’t know how it works. So they “disassembled” one of jackets they found, and discovered that it consists of bird fluff.
And this is how they reproduced heat saver thing. They made a building with walls out of fluffs cemented with clay. And got little progress. So they tried to use glair instead of clay, but still too bad.
Only 128 years later, when they advanced on heat theory, they understood what was wrong, and made building with hollow walls, but filled with flair.
A bit later knowing theory and learned chemistry and gas dynamics they stopped to kill birds, and replaced flair with synthetic heat insulation fiber.
Well, if we advance on how our mind works, we perhaps find a better use of artificial neural networks, or may be replace it with better concept?
