But regarding the topic of what it can be used for... yes, I see people talking about doing healthcare with blockchain, or BP using blockchain, or archeology using blockchain, and people asking about how to learn to use blockchain for their next random startup ideas, and I start wondering if I'm going crazy. To me it seems basically like asking "could linked lists revolutionize healthcare?", or "could Dijkstra's algorithm help end global warming?" which sounds like a completely nuts question to ask. Am I just missing a huge, fundamental part of the picture? The whole thing just doesn't make sense to me.
Well, yes, they certainly could, even though that's an extremely vague question from someone who might not even understand what they're asking.
If you're interested in hearing about blockchain's potential from a business and society perspective, there's a bunch of material, but for example the latest Andreesen-Horowitz podcast episode was about "why crypto tokens matter".
