I like this a lot:

"Blockchain and cryptocurrency are 5D ideas."

I run into "3D thinking" all the time. This is especially true in startup finance. I'm trying to get funding for a decentralized computational mesh. It's not exactly a blockchain, more like Iota's tangle. But it is a perfect fit to the ecosystem and fairly screams to be tokenized. The traditional startup trajectory in the US just doesn't see the disruptive nature of blockchain and tokenization. They only see the volatility and fear the scams, frauds, SEC regs and silly ideas.

This mesh we're working on is definitely 5D. If we can keep the lights on we hope to go public with the white paper 1Q 2019.
