"I will give you my prediction. Within 5 years, a distributed blockchain world brain will arise that will bury Amazon, Google, Facebook, Twitter, and YouTube." - Robert David Steele, Sep 2 2017

Where Steele is wrong is that the distributed world brain won't be built on blockchain. I'm sure it will include blockchain as a technology. But, as @cryptoquick correctly points out, you can't use blockchain as the basis for an application deployment platform, because storing data on blockchain is too expensive.

Arcjet is a proposal for a central and fundamental component of a decentralized world brain. It's an application deployment platform. I think it's a brilliant idea. Good thinking @crytoquick!
