I for my part believe that modifying the existing - Mach is a more promising approach - <Pete-J> as i understand man power is something you need - and by spreading - out the developers just makes the progress more slow - <antrik> but even if it *were* to be replaced one day, it doesn't change - the fact that we need it *now* - <antrik> all software will be obsolete one day. doesn't mean it's not worth - working on - <antrik> the vast majority of work is not on the microkernel anyways, but - on the system running on top of it - <Pete-J> ahh i see - <antrik> manpower is not something that comes from nowhere. again, having - something working is crucial in a volunteer project like this - <antrik> there are no fixed plans |
