This might be a surprise to some, but the highly paid engineers who invented the internet did not have access to the internet when they were children. Correlation is not causation, and in this case I can't even imagine the causal link in your claim.
Also until extremely recently, almost no one saw adult material unless they found a magazine of utterly tame (by today's standards) printed nudity.
See my other comment below for a more detailed answer but: no, my claim is not that I needed porn to become the engineer I am today. But the level of restrictions proposed by the top level comment in this thread would have, and it seems blocking porn is a driving factor in those decisions.
Social media addiction, etc. can be helped by restricting time without restricting access.
What would you reply to the person here[1] who wishes they had restricted access instead of restricted time, because restricted time hindered them learning to code?
