You think it won't go back to these old ways? They are no longer the way forward?

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.

Great insights Chris. You make some great points and it was the same for me growing up. I remember the time dialing into a BBS! OMG! !LOL !CTP !ALIVE
