They said same about video games but it turns out I didn't just want to play them, I also invested crazy amounts of time learning how to make them. Best time to spend crazy hours pursuing something you care about before the busy schedule of an adult saps all that away. It got me ahead. Not everyone just wants quick fixes.
The difference, I think (as an "over-user" of computers all throughout childhood) is that there were no basis for "they said same about video games", but there is a lot of basis for "social media is a net bad" now.
Do I believe the UK is doing this for the right reason or the right way? Absolutely not. But I also don't agree with the comparison of now and when I was a kid/teen.
