I don't think he intended to imply a correlation. But people do seem to use video games and television as a crutch to keep kids entertained at the expense of more enriching activities.

I think it all depends on if the kid is happy with occasional computer and TV use. Personally I think I would give my kid easy access to the electronic devices they want. If they want to do a lot of reading that's great and certainly encouraging, but there are more paths to achieve similar intellectual curiosity than just reading, computers in general, programming, games, certain TV shows, movies and documentaries.

My first computer access was to a DOS machine. I don't think it had any effect on my reading skills, since at the time I didn't actually speak English.
