I’ve been using Cinnamon for most of the last decade, but switched to Gnome3 recently, heavily customized to work like Cinnamon. Basically because Wayland is finally stable enough to use.
If Cinnamon gets Wayland support working well, that’s my choice. Otherwise I’ve got some Gnome3 configs that make it work pretty well, and I’d happily run it into the ground too.
The way Java is practically written, most of the overhead (read: inefficient slowdown) happens on load time, rather than in the middle of execution. The amount of speedup in hardware since the early 2000s has also definitely made programmers less worried about smaller inefficiencies.
Languages like Python or JavaScript have a lot more overhead while they’re running, and are less well-suited to running a server that needs to respond quickly, but certainly can do the job well enough, if a bit worse compared to something like Java/C++/Rust. I suspect this is basically what they meant by Java being well-suited.
