I think it is a useful thing to be teached in school too! I see it is very effective, because it targets real life apps and daily usage.. An example is the upcoming ARROUND project. This is practical because it aims to combine the augmented reality industry with blockchain. So as we may already now, there are many tuts about augmented reality, but with blockchain this will be more powerful! So, yea, crypto/blockchain is good to be teached..
Exactly! Time will come that everything that we will do will go thru a blockchain and not just cryptocurrencies. We definitely don't want the next generation to become shocked of how technology will be shocked in the next few decades so the earlier that they are taught about it, the better.
