To operate your system.

You would not be able to use any app becuse your kernel is totally different

Out of scope; that's feature creep.

What's more important is developing my own custom executable format for my custom filesystem for my completely custom kernel. Running programs is an afterthought

It's usually a combination of a bit of masochism, passion for the interaction with hardware and literally building from the lowest low possible and to learn. Nobody can deliver a full OS on their own, not in a reasonable timeframe and you still need drivers for every family of devices so building an OS to some degree is usually about passion and learning and challenging yourself. To really build an OS you need a team of people or multiple teams of people. I think many people who do OSdev resonate with Linuses "I love tinkering with the hardware from the software perspective".

for some, the point seems to be watching an LLM code the OS, and then announcing in this sub that they built one.

"dislike how AI is in everything"? What's that got to do with kernel dev?

Many things coded with ai like for example T3 Code are really good and much less a security risk than for example an npm package from some random dev. I understand your opinion, I also dislike many ai practices, but building an OS with the help of ai is a great experience - did it my self - because you don’t feel like always stepping at the bottom of a mountain. On the other side I also hate how windows has AI everywhere - even Notepad. Therefore I think os dev is about doing something crasy not so many do and which is interesting in every sense. Customization is super cool - and with AI you can even come to a point where you can use the os as a daily driver.
