yep, I totally disagree with this guy,
1 the internet changes the landscape in which these things move and grow, looking at precedents is difficult because of this
2 blockchain is revolutionary and still very very unknown, the market feels huge to us in it, but 99% of people don't even know what a bitcoin is yet.

I can see the mainstream system collapsing though, but that would clear the way for btc and its crypto cousins
