> I also think it's telling that even though Blockchain has been this hyped thing for 6+ years at this point, we haven't really seen it actually be used for anything outside of cryptocurrency, which in and of itself isn't used for much outside of speculation. On the other hand, machine learning is used in everything now and makes a lot of stuff better.
Did you know that the Neural Network has been around since 1958 [1]? Machine learning is not a technology that is just 6 years old. The latest AI trend is also not the first or second time that AI has been through a massive hype cycle.
The problem with the cryptocurrency space is that it's financial innovation. And just like financial innovation on Wall Street, this tends to draw out the slimiest people in society, because if you get someone to believe in your product they may well leverage their mortgage and throw their life savings at you. It's crushing to see people do this, especially because pretty much only the malicious projects get hyped up that much.
But that doesn't mean that there isn't any truly groundbreaking innovation out there. Cryptocurrency changes the fundamental scalability of society. A key bottleneck for human society is trust - at some point a system gets large and corrupt, and it becomes difficult to keep bad actors from imparting a large amount of negative influence. But cryptocurrency allows us to design systems that don't require any trust at all. They _cant'_ be corrupted, because a combination of incentives and cryptography keep everyone safe.
As this blog post shows, there are still a lot of rough edges out there, but the technology is innovating rapidly. I do think the hype is probably 5-10 years ahead of the technology, but in the grand scheme of technology (think of how long it too Arpanet to mature, or Neural Networks to mature) that is not much time at all!
