I don't understand why it's now so important to teach our children now about Stablecoins. There already some threads here that want us to teach our kids about crypto currencies and their benefits. It's important to educate kids and prepare them for an independent life, but in my opinion, this should be done more general and not specific to stablecoins. Why not teach them about money in general and how to be use different form of payments in a secure manner? We should be open about all the different types of currencies out there and let our children make their own choices.
I guess maybe because stable coins are like the traditional currency that we use IRL. But yeah you are right. There are also lots of threads which concerns about teaching our kids to get involved with crypto ( non-stable coins ). Any of them are important but it's only optional for a while since we may only waste time ( judging on the kids capacity to digest what they have learned ) which we can use better on a more important thing.Don't get me wrong, if our children are interested and want to learn about it then we should encourage them and teach them about it. But if they are not interested in monetary topics like most kids that I know, it's hard to teach them. The problem with forcing ideas on to children that they not interested in is to make them hate it and never want to touch the topic.
Teaching kids is different from how we teach the adults. We need to use materials which kids love so that they will never be bored of the subject. Some might still dislike it but their interests can still change later on, so we shouldn't give up easily. 
Gosh, I can't remember his name!
