Been telling my friends and family with kids the same. 

If one of the parents speaks a second language, then sure, teach it to them at home while they grow up. 

But instead of sending the kids to a french or spanish school, get them to learn computer language.

Language is just a communication protocol. You want them fluent in the most popular language networks.

If you're already an English speaking family, why spend time teaching them Spanish when they can learn coding? It'd be akin to them learning how to use Cardano instead of Bitcoin.
