I wouldn't say it's equivalent, after all, blockchain is a layer on the internet. But it is common for people to underestimate the impact of technology in the long term. Just as the dot com bubble left people disillusioned with the internet as a platform for commerce, so too is the current state of blockchain. It will continue to evolve, it will continue to grow, and something will rise up and change commerce in a dramatic way. I'd argue that the industry has already come a long, long way and it still has a long, long way to go.
