Just as bitcoin took more than 20 years to emerge from primitive ideas, private messaging has taken a long time to develop to where we are today.

Contrary to what people think, development in computing is slower than it seems for certain fields.

Although you are right that many projects are left half done, that's why I insist on SimpleX, it solves most of the problems we have in the current private messengers, it has a polished interface and works really well.

It would be a shame if it got lost in the crowd.
