The most notable difference between TV and computers of various sizes is it's interactive vs. passive, so the "reducing screen time" needs more nuance to the discussion - likewise Roblox etc together as a family sounds lovely vs. isolated dopamine hits from Instagram potentially allowing your peers/strangers dictate how you should feel about yourself (wrongly in either direction).
This reminds me of all the screen time I had as a kid with my parents, taking turns on single player games (a life or a race). A lot of time spent thinking about how the next turn would go, who would be better at this level (my mom was great at some Zelda temples and I was better at others). Way more thinking happened than any other TV activity.
My father mentioned he noticed that when I played video games with my peers as a child, it was very much a social activity. I think it somewhat changed his paradigm on the medium after the 1990s having a bit of a moral panic on the topic.
