Кажется уже не получится "улучшить" эл. почту. Нужна новая децентрализованная технология. Как сделать её простой для обычных пользователей? Как убедиться, что никто не сможет украсть или заблокировать твою личность? Идентификации просто по публичному адресу уже давно не достаточно.
Мессенджеры полностью заменили почту в плане общения, возможно их надо доработать?
