IM won't replace e-mail due to two important things you seem to be neglecting (for a long time :) ). They are: * human psychology and ways of working * lack of features on IM (and this problem is bigger than implementing crypto in e-mail). _ Let me describe them more, starting with humans: * we love to separate things in our minds, like work/home linkedin/facebook profiles that will never merge, no matter how much money fb will pour into fbworks or others. * we assign e-mail, an aspect of 'longer asynchronous communication'. We desire this 'asynchronous' aspect, allowing replying us with a delay. We demand that a separate (sic!) tool with such characteristic (and publicly agreed typical use) exists * we need communication tool for longer (like this or yours post) exchanges, where MULTIPLE people can participate. We need to able to put into one message 10..20 minutes of work. And no, we will not be publishing and exchaning academic papers (read attachments/separate documents) for such discussion to happen. * it can't be tied to instant/short comm tool. _______ Features: * we need (must) to have a searchable archive of this communication tool, instantly available, surviving device changes (telegram and signal are out), and multiple years to store * this tool must be connected to publicly available namescheme of internet: domain names - no IM are, they create they own space. This is ultra crucial: I must be able to send and receive information to a participant who I know only a domain. Like for examples yours: youagain@latacora.com * I need to be able to talk with multiple people, knowing who they are (domains), and @Immuppet1980 or @894984320123 is not, while tptacek@latacora.com is * we need to to have multiple addresses all being accessed with relatively small number of clients (read 2). Welcome to the IM hell, when if you're 40 and have friends from around world you need to ahve: signal, telegram, fb, whatsap, sms, ghangout, alo, and I'm not even started with asian tools! This sucks. _ So no, while I share your despise to current crypto-email state, the proper way is to try to secure e-mail, not to get rid of it. Incrementally, getting rid, one by one all bad things of it. There is no bing bang approach.
