I don't know! Probably not soon. But what if one day emails become obsolete for some reason?
Remember when we all used SMS and now most people use WhatsApp or other Apps. I didn't send SMS for many years.
Look how computers and the internet have developed in the past. We are now talking a lot about web 3.0. When I was a kid there wasn't even internet. I used to surf in mailboxes which you had to call with your modem. I grow up with a walkman, then a portable CD player, then an MP3 player, and now everyone uses their mobile phones to stream from different services.
There is no way back even if you wish.
