It's absurd to equate books and social media to being akin. And you're being facetious in your comments.

What if you are wrong? What are the risks vs rewards?

The main risk you have presented is a supposed negative effect on children's development. I am not convinced that there will be a negative effect at all.

On the reward side we have potentially curing most major disease, automating labor and freeing humanity from having to work for a living, as well as perhaps generally advancing science at an unprecedented pace. And of course improving education.
