Conviction requires a huge body of knowledge which can’t be acquired in a conversation. I imagine you and your brother have different interests, which lead you to different knowledge of the world. The conviction you feel is just the tip of the iceberg, though you don’t hold it consciously, most of your knowledge and experience will be hidden in your subconscious which forms your opinion and either makes you more or less able to digest the conclusion you’ve made. I’m not sure there’s a way around self motivation to learn about it and spend 100’s of hours learning about it. You can get people to follow along, agree and even buy some bitcoin by presenting the tip of the iceberg. But conviction requires a solid foundation which cannot be attained second hand. I think the transition to a true bitcoin standard globally will take longer than we think because of this. Even though I would like to think it’ll happen in a decade or two. I think this is going to be an intergenerational transition like many groundbreaking foundational things. The internet was different because it didn’t swap out one thing for another it developed alongside and complimented many real world businesses before slowly shifting over. Many physical stores had web stores too, this legitimised the experience for many older users who could now buy things from companies they trusted, the transition was smooth. We will see treasury companies and banks legitimising bitcoin and this will act in a similar way, but even that is a large paradigm shift compared.
