For getting a grip in current web development, I would recommend fullstackopen.com - it’s a free online course by the University of Helsinki and starts from basically zero, and gives you a lot of insights into web dev.
It may take some time, but it’s really worth it and an overall great course.
Maybe we are not done yet with understanding how our biological computer works.
On topics like this, I like to think about bacteria:
Before microscopes, it was unimagible to have little organisms on us and everywhere around us. People have been labelled crazy for believing that there is a whole small universe of organisms everywhere.
Then came microscopes, and suddenly everyone could see it for themselves.
What if we just don’t have the right tools to make our magic sauce, spirit, soul, whatever visible to us yet?
