The TL;DR is: - blockchain systems still need trust; - security is not solved; - blockchains are overhyped and most followers don't want it for the problems serious actors try to use it to solve. - it has many issues (need for infra, require tech knowhow, etc) I agree, but I still don't see how it's crapy tech, nor how it's a bad vision of the future. You have an system that make auditing easier, with one place only for the data to be read and written and yet robust enough because of the duplication. You have transactions logs tided to identities you can fake organised in a timeline in an open format that is not only very well documented, but being actively tested right now on the field. You have hundreds of start up engage in a Darwinism race to find out which use case we can make that's worth it on the long run. And finally, the tech has enough impact to force state actors to create new laws, financial actors to adapt and a huge amount of money to be invested by a lot of people. So on one hand one very interesting concept. On the other hand, pretty much hate for the sake of hate.
