The problem is what would be the point of AOS on a x86 processor? Linux works because it is free and has software support. AOS would cost money and have no software support. As for supporting old architecture, you're right there is no point in supporting the classic or even Amiga one archetecture and as AOS hos nothing to offer anyone the AOS for x86 is pointless. As an OS it offers no innovations and doesn't measure up to any of the newer OS so why bother? It would just be an exercise in futility and a backroom project for fanboys.
