I'm using "internet addiction" here in a loose sense. Think of all modern hyper-engaging online services: TikTok, MMORPGs, social media, video games, porn, etc.
I think HN users might be especially aware of how addicting these can be, so do you take any precautions to help your children avoid falling prey to them?
We have never had limits on anything. Screen time/content unrestricted. Probably dozens of times, maybe hundreds, we have had "the talk" about how there's a lot of weird shit in the world, internet included, and it's better to know about that stuff and how to deal with it than to create a temporary secure enclave at home where it doesn't exist.
We especially didn't want to pawn off our responsibility as parents onto their future 18-year-old college-bound selves to learn how to deal with excesses. Since the moment they could point, they've been given the opportunity to make mistakes with excess. They've fallen thousands of times, we've picked them up thousands of times, and now they're pretty good at not falling.
You can guess that I love CI/CD, stable trunk, etc., in my day job. My attitude as an engineer/parent is you'll never make bugs/threats go away. So make sure you and your team/family are experts at dealing with them while they're fresh and small.
