This is very extreme take. I learned to program at age 10. It is an amazing tool for mind development. Had to invent sine and cosine tables to make my computer games, before even encountering the concept at school.
Some kids learn to drink and smoke at a that age too, and many turn out ok.
Keep in mind that alcohol is also a carcinogen. Similar to cigarettes, even one drink shouldn't be tolerated. Even if a certain amount will have no ill effects on average, impacts on individuals depends on individual factors, so one harmless drink for you might be one deadly drink for someone else. It is poison.
That said, I don't judge anyone who uses substances. But there is no tolerable threshold to giving children poison.
All 3 were a total hotbed of bad influences for a child: Team Fortress had trade pub servers with people doing sprays of literal CP and wearing custom lewd skins to harass users with them - and people with very questionable social skills and intentions huddled up in realtime microphone comms with children, Roblox's predator problem for the last 14+ years (at least that I can attest) is suddenly en vogue now that they're a public company and there's stock shorting to be had, GMod is still the community with the most colorful vocabulary I've ever encountered - plus grooming. And much more.
Indeed, you can (and I did) get burned by these actualities when exposed to such communities in your youth - and it can cost you real money, real time, real idealism/innocence, and real mental health. However, I think being exposed to softwares, systems and games that inspired curiosity and led me toward a path of WANTING to contribute brought me to this software development career and life path, and it would have been much more inaccessible and unknown to me in any other way. And I favorited a comment from another HN user a few days ago that goes in astute depth on why that path can only be organically introduced and self-governed [1].
I referred to these places earlier in my comment as "bad influences". I think the single-most powerful thing a parent can do tasked with this dilemma - especially during an upbringing in systemically hard, uncertain, and turbulent times - is teaching them how to identify, avoid, and confront bad influences. Equipped with that, and knowing how to handle yourself, is of utmost importance.
It doesn't matter how good the tool can be, what matters is how it actually is used
