I think it is good for children to learn about Bitcoin and blockchain, but not because they are our children or our little brothers, but because learning how a technology focused on self-sufficiency works can give more emotional security and develop growth. Whether we like it or not, we live in an increasingly technological world, and the sooner these children learn to independently use the tools that can give them some privacy and financial freedom, the sooner they will learn to be autonomous.
Unfortunately, the time in which today's children grow up is completely different from the time in which people who were born 30 or more years ago grew up. As far as I can see from the voting results, even 70% of those who voted agree that children should be educated about Bitcoin after the age of 12+ or even regardless of age.
I have already written that this education does not have to mean that we teach children some complex things, nor that this education should be forced in any way - children at that age learn best through play, and Bitcoin can always be explained in a simple way.
It is always important that when we want to explain to anyone what Bitcoin is, we do it in the simplest possible way, because otherwise people often get discouraged very quickly if you tell them about how to create a wallet, save a seed, adjust the fee for a transaction, and the like.
When children start school, they first learn to write letters and numbers, which is a prerequisite for everything else - it should be the same with getting to know Bitcoin.
