I'm that social in SL these days, that I've helped the last noob in need of help somewhere 2015 or so.
So noobs are still a thing than?
I've read somewhere that four out of five first-time SL users only log in once and then never again.
My guess is that those who have never used any kind of MMO are repelled by the lack of WhatsApp-grade ease-of-use. And those who have are repelled by how SL surprisingly turns out
not to be an MMO, no quests, no stats to grind, no story mode, nothing telling them what to do.
A while ago, I've watched a video made by some young fellow who probably already had some MMO experience. It was painful to watch. I think he had read about SL and how it started booming again during the pandemic. And he tried it. Without reading up on it. When he logged in, he knew nothing. So he derped around aimlessly for several minutes, not even bothering to read anything on-screen, clearly expecting a tutorial quest or being railroaded like you are in MMOs. At the end, his verdict was that SL sucks because he didn't understand it. He quit before he could find out that many things he may expect to be taken for granted cost money in SL.
Being a mentor must be much harder nowadays. Aside from the total newbies, you'll have to deal with the occasional 20-something know-it-all into whose head you'll have to hammer constantly that, no, SL is not Fortnite, and no, neither can nor should everything in SL be done the same as in Fortnite. And when the mobile viewer goes gold, they'll might have to deal with people who have discovered an app named "Second Life" in the Apple App Store, never having heard of that name anywhere, and who have never in their lives touched a desktop or laptop computer. If they figure out how to chat, they'll still ask mentors the most basic things such as how to make their avatar walk. And the mentors will be the "old guard" that doesn't know how to steer an avatar using the mobile app with no physical keys at all. They'll have a hard time telling these newbies that SL is, in fact, not just a smartphone app, and most people use it on a "real" computer.
