I know this is complicated (it isn't), but parenting requires a dedicated investment of time. Or, just get them an iphone like most other parents and ignore them all day. Or maybe you can hire a surrogate parent to teach them since you have more important things to do.
This thread just reinforces, to me, that people who claim to write software skew highly autistic. Nothing I said here is complicated, but when you are a person with exceptionally low social intelligence spending more than 5 minutes a day with your kid might really feel the same as 25 hours.
I am not kidding when I say just get your kid an iphone and pat yourself on the back. You are either trying to teach your kid something directly with your time or you are just expecting them to want to figure it out themselves because you can't be bothered.
