Flatpak very likely is not the future indeed but it seems like a good step towards it. Of all the arguments of the author I only agree with the RAM usage part. It's true that having containerized apps will lead to much more CPU L-cache trashing which can dramatically reduce performance if you are regularly starting and stopping programs. This is indeed a problem that needs solving. I can envision a NextFlatpak that keeps a global cache of versioned libraries (kind of like Apple does in macOS) so as to try and reduce RAM usage as much as possible. And I agree with the author on the startup time (which is also related to memory usage and CPU cache trashing). That too is a problem that needs solving. The rest of the arguments though, meh. Are you seriously arguing the case that we need to respect 120GB NVMe SSDs because they are "expensive"? Really? I spent 255 EUR (288 USD) on a 2TB NVMe SSD (and it has 3210 TBW of endurance, one of the very highest of all NVMe SSDs!) for a spare dev laptop and I am convinced most devs would have no trouble making that purchase any time they get the whim about it. And even people in my poor country, people who are mind-blown by their new 1300 EUR salary, can still plan financially well enough to afford a new iPhone 3-6 months later. So again, not convinced here. As much as NVMe SSDs are expensive per GB, they are still well within the grasp of most users who actually need them. As for security, it seems the author overstates the efforts of distro maintainers. They do an admirable job, this is well-known, but they really can't be everywhere so him praising them so much might be a bit misguided (as do other posters here). Flatpaks don't change the game in almost no measure there, especially if they get properly isolated (as another poster alluded to: I want to be able to stop all internet access to an app; just one example). And none of what the author states will stop a malicious app that's not in a container so really, what's his point there? That the Debian maintainers inspect 100% of all apps and will spot a malicious calculator? Come on now. And the rest of the post is just ranting and having a beef with a few things, which is clearly visible by his change of tone. Call me crazy but such an article can't be called convincing. ¯\_(ツ)_/¯
