Ask HN: ARM-based Linux laptop business?

This is at the "is this even possible" stage. So the end goal would be to build a completely FOSS laptop using Risc V with zero proprietary blobs but after briefly exploring Risc V, the ecosystem is still way too early to build anything for consumers/enterprises as someone new to the space. So that's why I want to start with ARM. Note that I have zero experience doing any of this. My questions: - How well does linux run on ARM based processors? Will the existing x86-64 software/packages run by recompiling from source or are there any additional complications in porting software over. Will KDE/Gnome run out of the box? How is GPU support? Looking at Raspian, the situation seems encouraging. - How do I go about learning about the hardware and software areas of building an ARM based laptop? Recommended resources? - How is ARM based processors' security track record compared to intel and amd's lineup? My brief googling suggests it's better and ARM does not force the usage of a ME/PSP. - Imagine I could buy a thinkpad x1 carbon like system with an ARM based cpu, install ubuntu and start using it like how one would use the x86 version. Would this even be possible? What are the potential speedbumps? - How do I actually design a laptop? Maybe start with an off the shelf solution like clevo? Any and all advice is welcome. I know I am grossly unqualified to do any of this, so please be kind.
