As far as Peterson goes, I've heard him point out the trend of young males paying attention to him and the potential link to feelings of dissolution/meaninglessness/lack of purpose. He seems to think these sets of hypothesis are on the right track.

Video games seem very similar to drugs in this regard. I've not seen evidence of video games being causal in any way, any more than drugs. I think it's more accurate to describe them as potential negative amplifiers; they're very easy to abuse because of how well they satiate the aforementioned feelings many people (notably young men) experience.
