100%. Most people I know, if you say the word protocol they'll think of the Royal Family before they think of anything to do with the internet.

It's the same problem the early web had. Mosaic created a good browser, onboarded a bunch of users, and then people thought the web WAS Mosaic. That was fine for then. But, today, people may not understand hypertext transfer protocol, but they sure do know that anyone can make a website.
(Same problem of Mastodon vs. ActivitPub/Fediverse, btw)
I'm not saying the average user needs to understand this right now, but when they do is when we will know we're winning. Some people want to build the next Mosaic, and that's great. I'm focused on the world wide web.
On that note, this which I just stumbled across is a good read, academic paper caveats deployed: https://arxiv.org/pdf/2505.22962v1
