This is exactly right in my opinion. The dotcom era was all about the decentralization of information, whereas blockchains are all about the decentralization of trust. Contrary to the OP, I believe that blockchain technology really started in the first alt coin boom around 2012-2013. That's when the tinkerers came out. I think blockchain infrastructure is still very early days, and scalability is still among the biggest problems to solve currently, but it's definitely being worked on and it's solvable.
