Here’s the quote in context, slightly less vom worthy:
What do you think about blockchain?
It’s really interesting and we spend a fair bit of time looking at blockchain. We’ve had a lot of partners and customers building blockchains on top of AWS and services for others to use on AWS. We are watching it carefully. We talk to customers, and they are very interested in the concept, but we don’t yet see a lot of practical use cases using blockchain. We don’t build technology because we think the technology is cool, we only build it if we think we can solve a specific customer problem, where building that service will solve the problem. So far, with the vast majority of use cases, there are other ways to solve those problem more easily.
