Right. I mean how many people know how the engine of their car works?Most of them don't know and will never get it. But they know how to drive it and what is the benefit to it instead of riding a horse.
But everyone needs at least a little bit of knowledge. You don't need to know how the engine works, but you know that there is a thing called 'engine', that it requires a fuel, some maintenance etc.
No one will switch from riding a horse to driving a car without the very basic idea of how the car works.
Same with Bitcoin. Without explaining the concept of decentralisation and P2P network, most would still imagine that Bitcoin is some sort of company that sells 'currency' backed by nothing to the naive.
Sure, good explanation (not quite correct, since wallet on your phone doesn't really contain any currency). But majority would struggle to comprehend that you don't need any bank or other entity to issue and control the currency.
I know several girls and boys in my clique who have absolutely NO idea how a car works! But they all have driver's license and can drive a car. But really absolutely no knowledge about the technic behind that.
Or use the internet as example. Most people know how to use a web browser to surf in the web. But ask them if they know what happeneds in the background when a webpage loads on the browser. The border gateway protocol routing algorithm that takes the TCP/IP package that your browser sends, uses the IP adress etc.....95% of the people have no fucking clue! But they know how to use a web browser.
We have to make bitcoin more user friendly. It feels a bit like in early 90s of the internet now without browser and search engines. I'm sure there are companies working on that.At least I hope so.
