Earlier quoted context omitted.
Email might already be 'culturally dead' though. I guess my nephew might have an email address for the occasional password recovery, but the idea of actually communicating over email with other humans might be completely alien to him ;) Similar in my current job btw.
Ok, I get how one might use a variety of other tools for informal communication, I don't really use e-mail for that any more either, but I'm curious, what else can you possibly use for work ? With the requirement that it must be easy to back up and transfer (for yourself as well as the organization), so any platforms are immediately out of question.
I see a difference with enforced email use and voluntary, for work. At my company everyone uses email because it is mandatory. Human-human conversation happen there without issues. But as soon as I try to contact some random company on email as an individual, like as a shop about product details or packaging, or contact some org to find out about services - it's dead silence in return. But when I find their chat/messenger they do respond to it. The only people still responding to emails from external sources in my experience are property agents, and even there the response time is slower than in chats.
