The biggest life lessons I learnt from Deep Learning

The neural networks in deep learning are generally considered to be similar to the neural networks we have in our brains, albeit a much simpler versions. This similarity helps comprehend the deep learning neural networks easily. I have always seen the similarity to be used only to comprehend the deep learning neural networks and not to understand our brain from what we learn about the deep learning neural networks. The points below do not have a logical deduction but mostly my observation and intuition. The lessons I learned about life from neural networks are not new.
