I’m glad you censored r*sponsible.
I don’t think it’s video games though, they tend to be intensive experiences that are only sustainable for a few hours at most - I don’t think most young adults are whiling away their lives playing GTA (although some certainly do). I think the constant dopamine microdosing from social media that’s the much larger issue - it makes everything ever so paler in comparison, especially over time. Porn is a similar kind of dopamine hit (maybe akin to a vodka shot while social media is a dripfeed of wine), so I do agree with you there.
