TL;DR: Please share links of public presentations about the Fediverse that provide an introduction to non-tech-savvy people showing the benefits and some examples like Lemmy.

Recently I have discovered Lemmy and with it the Fediverse - sure I heard of the Fediverse and Mastodon before, but I never really looked it up in detail, because it sounded like one of those projects that are really cool, but do not work because everyone keeps sticking to the big tech giants. However, now that I tried Lemmy for a couple of weeks, I feel like this does work and would like to spread the news a bit more.

For that I am looking for a nice set of slides that cover the Fediverse - and some examples like Lemmy - in such a way that students of different sciences can understand its purpose, advantages and disadvantages. I am aware that this is a bit low effort on my part as I could create such slides myself, but probably someone with more skill than me has done that already so...

EDIT: I just found https://u3acommunities.org/is-it-time-to-move-to-the-fediverse-followup/ which is very close to what I am looking for. Sadly, I can't find a download link for the slides to make some small edits (I feel like just using someone else's slides is fine as it is only for a private audience).
