Proof of work vs. Proof of stake ..

is the key here. You don't need to mine - or have mined a currency - to operate a blockchain. Merely be able to prove to the chain your right to participate.

Having done quite a bit of research into blockchains, I'd say the shark to expert ratio is about the same as for "AI" and "Big Data".
