Well to be fair, transferring money instantly would be pretty great for 2020.
I mean, the only way I can pay rent to my landlord in 2020 is by having my bank send them a physical check that takes 5d to arrive (during which time no-one gets any interest), or then use multiple Zelle payments since I have an artificial cap that is lower than my rent.
Yes that's true now, but what about in 1997? That's what year it is in Ethereum now.
