As an operating system for a dedicated, single purpose server this may be okay. As an operating system for mobile phones, this may one day be alright (when phones get about 12 cores). As an operating system for workstations and desktops, this is probably the worst idea I have heard in a long time. It sounds like a hipster version of multidos. At one application per core (or at least I think that's the idea), you are severely limiting the ability to multitask. So, on an 8 core system I have one core running the exokernel (1), another core running a gui (2), another core running an audio application (3), another running my web browser (4), another with my editor (5), another with git (6), another with a torrent going (7), and another with email (8). Due to the description, I am hoping that the GUI using a core and other applications having access to it is possible. I also hope that audio services don't need a core, or else the audio application developer will need to reimpelement OSS4 and/or ALSA in his/her application. That's just about idiotic... oh well...
