I also prefer science and reason to faith and religion. With that said, I take full responsibility for driving this particular thread of the discussion in this direction.
I hope our discussion has been cordial, and hasn’t muddied the overall post. I didn’t mean to drag you or anyone else into this, and I’m sorry if this discussion caused any harm or triggered any negativity. I’ve experienced religious trauma in the past and I know how debilitating it can be.

Email is absolutely still used massively, especially in the business world. Even if someone is accessing their emails in a browser, they are still being sent with SMTP behind the scenes.
There’s also SSH, NTP, VOIP, FTP, BitTorrent, and probably more that I’m forgetting, that all have varying degrees of usage today.
Don’t get me wrong, HTTP is certainly by far the most used protocol, but it is in no way the only important one that would be difficult to replace.
