Something I've been thinking about with any blockchain technology is that it will likely end up sitting on top of the current Internet platforms, but still behind the scenes and hidden from both enterprise and consumers.
If so, will new blockchain-based startups disrupt industries and create their own competing consumer services, or will the incentive to dramatically cut costs (labour mostly) push existing industries to transition their operations to run on a blockchain?
eg the average user should never come across the word "bitcoin", they just continue to transact and pay with "dollars" as they already do. But behind the scenes, the entire financial system operates on a blockchain.
eg2 existing companies looking to cut costs could automate much of their staff by transitioning their core database and systems to run on a blockchain. However all customer-facing UI and interactions would operate as normal. A company like Uber could run entirely on the blockchain as a DAO, and have a small team responsible for maintaining the consumer-facing apps
