The solution to this problem is actively parenting your kids. Take them on hikes, start a hobby with them, bond, etc. Letting the internet babysit your kids is the precursor to internet addiction. If you put in the work, then you won't have to worry.
This is an excelent answer, which makes me itch to push a little further.
I suppose OP (and you) are not "internet addicted", and I'm pretty sure it's not because someone is working hard to keep you from the internet, but because you have other things in your life that you enjoy or understand are critically needed.
Kids aren't that different. We might need to push them first so they discover new things and find what they like, but they'll definitely come back to you to go hiking if it they had a blast the last time.
I'm not sure it's really "put in the work", and I like a lot your "actively parenting" part. The crux is really to have fun with your kid, and if it's fun they'll do it again, and again, and again. And they also have a sense of responsibility, letting them fail and be remorseful when they didn't do their due and watched youtube instead is often a good enough strategy.
