Appimage for me ticks all the boxes for cross distro package as its very portable, simple to run, what are devs trying to do when creating snaps and flatpack?
Aah yes, appimage, flatpak, snaps, progressive web apps, electron apps... The cross-compatibility of the lazy 21st century developer, where a simple IRC-like chat client comes with an entire operating system or an entire browser (which itself is an entire operating system too nowadays), takes up half a gig of disk space, and starts up in over 10 seconds with a multi-gigahertz multicore CPU.
It’s been that way since the dawn of computing. Developers will push hardware to its limits and the hardware people will keep making a faster chip. A lot of software was laggy as hell back in the day. Not to mention, it didn’t have any features compared to the stuff now. Plus our shit would crash all the time and take down the whole PC. Sure, you run across some shockingly fast and good apps but those have always been few and far between.
