This author is either lying or has no idea how blockchains work.

Blockchain will administer similar shocks to insurance, healthcare and all mass payment systems. Blockchains can do nothing useful for insurance and healthcare. Publicly accessible databases with auditing and security mechanisms (double-entry accounting, git, and merkle trees predate bitcoin and blockchains) and a public API which will likely be branded as blockchain tech will always outpace any sort of PoW/PoS style blockchain protocol replicated database. Intermediaries in the service industries will face a new world in which their routine functions will be performed by machines, programmed by artificial intelligence, while the blockchain becomes the new means to do business safely, faster and less riskily. This is just a poor writer grasping at buzzwords. SciFi writers at least try to paint a more detailed picture to fit their buzzwords in. Blockchains are notably irreversible, so there's an inherent risk and immense inefficiency in their use. the blockchain economic model is more efficient and more effective the larger the network. This is absolutely false. Blockchains are insanely inefficient as a design feature attempting to prevent a single group from having write access to the database. As the network grows larger and more computing power is added, the effectiveness and efficiency goes down and transaction throughput remains the same (blocksize bandwidth usually has a hard limit, in rare cases blocksize can be variable and grow but this is unaffected by addition of computational work added to the network, granted the blocktime/hashrate consistency readjustment stabilizes)
