Now e-mail is going the same way. Communication with friends and family seems to have moved to Whatsapp, Facebook Messenger and a couple of other ad-hoc apps. Most of the email I receive these days seems to be people trying to sell me stuff or people trying to scam me. And receipts of things I've bought, ok. It is a pity, in a way, given that on those messaging applications you tend to stick to one paragraph or two, email lends itself better to long form and when looking for something you said or was said to you it is much easier to do that on an email archive than trying to slowly scroll backwards on, say, WhatsApp.
I suppose every step we take and every door we open and get through involve the giving up of the possible alternatives. With email you lose the thrill (a small thrill but one nonetheless) of getting an envelope with an exotic postmark from a friend you've long not seen. With the messaging apps you lose the ease of writing or reading long form. What's next? Purely emoji communication, like the Kinographs in Neal Stephenson's Anathem? I don't think I would like that.
