This is kind of erasing the author with your description of the issue. The reason that apps eventually require CLI to complete tasks is because devs think of CLI first and then produce a stop-gap P&CI over top of it. It is explicitly how devs in the Linux environment operate which creates a gap between CLI and P&CI. If apps were developed with P&CI in mind first, with CLI added after, this would not be a problem - and we know this because of every app developed for both Windows and Linux, which lack these gaps in functionality - or lack CLI entirely.
Your stance also de-emphasizes the difficulty of learning CLI for the first time. It’s not the most difficult thing ever, but it can be fairly frustrating. It’s not something you want to deal with when just trying to unwind after work on your PC, or while you’re trying to do your job at work. I think it’s pretty reasonable most people don’t want to have to learn yet another paradigm just to do what they’ve already figured out how to with a P&CI.
Being realistic, of course, this paradigm shift is not going to happen. Linux will continue to be only a small portion of total computers used by end users because of this, and various other reasons it’s found unpalatable.
I’ve heard that KDE and GNOME, however, are both at a level now where P&CIs are all you really need. I have not tried them myself, though.
Something that deteriorates the structural integrity of load-bearing frameworks /s.
Being serious, it’s another programming languages that is gaining popularity. Others can expand on why it’s good. I’ve never used it myself so I can’t comment in good faith. I also don’t have any experience with Rust-bros so I can’t comment on their code quality. I’ve mostly just been watching amused as they fight with the Linux development community.
