Hi! I think that the idea is certainly a fun one. There is a long history of trying to make a good parallel operating system. I do not think that any of the projects succeeded though. This article is a good read if you are interested in that. I am not sure why the economics of parallel computer operating systems have not worked out so far. I think it most likely has to do with the operating systems that we have being good enough and familiar. [0] https://news.ycombinator.com/item?id=43440174
