In the end, we all want massive use of z transations compared to t2t, and ideally t2t disappearance. I still think it’s about what we build on top of the protocol part that will make it move that way.
Forcing people to go one way never really work. People don’t like change being forced at them. We need to make people understand the need and change themselves.
Anything that is built on top of the Zcash protocol should make the z transaction the default or easier and better choice.
@nathan-at-least had a good example of such a success: Signal.
By the way, does anyone now more about how people started to transition from http to https?
(By the way, I guess http still exists, but the browsers now shift to https by default).
