What if you started from the other assumption?
Hopeful technology starts from the other assumption and keeps the receipts to prove the assumption still holds.
Cynicism is cheap because it costs nothing to hold. You can predict decline forever and never once be caught wrong before the world ends anyway. Optimism is expensive. It has to keep being right, in public, on a schedule.
Hopeful does not mean cheerful. It means being willing to make real design decisions on the assumption that people, given a fair tool and an honest interface, mostly do right by each other and themselves.
Visible price. Easy cancellation. Generous defaults. Trust people until reality gives you a reason not to.
Accessible does not have to mean condescending. The person on the other end will grow into the tool.
A hopeful assumption that cannot be falsified is a slogan. Every act of good faith here comes with a number that would have to move if the bet stopped paying.
Hope is not haste. Build at a pace where you can actually tell.
If that happens, change the design because reality changed your mind. Not because fear got there first.
Good. Now you have an assumption reality is allowed to disprove.
