Interesting article from Brian Armstrong. Definitely well worth reading if you enjoy thinking long term:
https://nakamoto.com/crypto-in-the-2020s/Among his predictions:
Privacy. In addition to scalability, I think well also see privacy integrated into one of the dominant chains in the 2020s. Just like how the internet launched with HTTP, and only later introduced HTTPS as a default on many websites, I believe well eventually see a privacy coin or blockchain with built in privacy features get mainstream adoption in the 2020s. It doesnt make sense in most cases to broadcast every payment you make on a transparent ledger.Yes he is just another guy in the line of guys talking about Monero but not mention Monero. You can hear this from Andreas Antonopoulos in every second talk. You can see this by all those that builds Bitcoin infrastructure and get feedback from the users. You dont need opaque ledger if you dont use crypto currency. It is really simple and most people dont use it. So they dont see the need for it.
I saw this article today from world economic forum
https://www.weforum.org/agenda/2019/01/these-3-technologies-will-permanently-change-the-banking-sectorThey clearly state that for users beside security privacy is most important thing, but latter on at what blockchain brings us praise its transparency. People dont want that!
