The author of the OP appears to have edited it to indicate that it's just crashing, and doesn't know if it's a segfault or just a panic. It appears there is some known potential for segfaults in tree-sitter, which is a native C dependency.
I have had treesitter crashes in the past editing markdown, causing helix to segfault, but the particular bug that caused my crashes has been fixed since years.
The thing about SPAs is that computation can be done in the customer's machine. That usually makes it worse for everyone, both devs and users (although sometimes it doesn't). I personally believe that we can create better experiences routing more pages with more imagination, but at times this industry is quite vocal on what "user expectations" are.
What has actually changed in the last 13 years regarding Whatsapp? Video. And I believe that's the reason why anyone hasn't actually challenged them regarding messaging: you can build a similar application with similar features with a rather small group of people (not saying it's easy, but it's feasible). But handling those pentabytes of bandwith shared every day? Actually _promoting_ the use of DIY video as the preferred communication media? That's something you can't do as an small shop. And that's, I think, why you cannot compete.
I decided to quit Whatsapp, which in Latinamerica is quite an outrageous move: that application is the communication channel for EVERYTHING: all families, all schools, all neighborhoods. I did it because I think Meta's main metric is actually hostile to their users: they want as much of your time as they can get from you, and they'll use are sorts of psychological weaponry to keep you inside. They were actually vocal about it in the past. There's zero reason to trust them. But why is it that no one has come up with a true alternative (although props to Signal)? Well, there's the network effect, for sure. They also employ very good engineers. But I believe the true reason is scale: it didn't use to be that way, but infrastructure costs are now inmense.
Not a public library -- their institution's library. The context here is higher ed students in poverty situations, and I've never heard of a college or university (that isn't online-only, at least) that didn't have a library.
But seriously, the poster is probably complaining about how most modern music is heavily compressed in dynamic range, so that it sounds better on crappy earbud headphones and smartphone speakers.
