Many people don't understand bitcoin because they don't understand software. And much less open source.

Bitcoin has been done by a worldwide top engineer, and it was done freely because of Satoshi personal values.

It would be weird that a top arquitect did a state-of-the-art building, for free and for all. But everybody would grasp the massive value of such thing.

Many have a hard time with that part. And its just the first steps, because then you need to understand the idea of unit of accounts and the concept of money to measure human behaviour.
