If you actually take the time to look for posts and communities about things you care about, you'll find more than enough of interesting people. It's just that there is no algorithm to feed you content, you have to be active in looking for it, at least initially.
I'm not necessarily saying you made this mistake, but plenty of other people who dip their toe in the fediverse do this - they get in, find nothing in their feed, they shrug and forget about it. A good start is to search for a few hashtags that match your interests, even add a follow for those if you see they're active, and soon you'll start seeing interesting people. I've been on there for years, and I'm always amazed at the small niche discussion threads I find.
There are many, many such great communities hidden all around the Internet - on half-abandoned forums, IRC channels, even Matrix rooms. One just has to wade outside the mainstream fascist asocial networks, and look for niche topics.
I think people are tired because people were catastrophising things Trump did 10 years ago, and it's like when a microphone clips because the gain is too high. If you were weeping into your Tiktok in 2016 before anything happened, and even while some good things were happening, it's hard to differentiate reality from hysteria.
Type 1 diabetes with the sensors and pump technology that this software being presented here fits to is not Everyman Joe stuff. Someone who can set this up and get this going is already burdened with the kind of analysis that the app can assist with.
