The computer OS is too important to be left to market forces and fickle managers.
There should be a worldwide effort to create a single free unified OS (with a metadata filesystem, and 100% scaleable GUI!) for everyone, which dumps the bloat and legacy code of old OSs (including Linux) and starts afresh. It won't happen now, or even soon, but sometime within the next 1000 years it is almost definite.
Such an OS won't drastically change over the years, but keep with a consistent theme (no flatland design!), only changing if a consortium of thousands of the brightest software engineers, mathematicians, scientists, and designers agree it's for the best. Everyone writes software for it, and there are no worries of cross-porting or compatibility issues. All software will be completely self-contained (no external libraries, or preference files scattered over the OS), and 32 bit would be a thing of the past. Searching for files and programs takes the OS less than 0.05 seconds in all cases.
I would dig that OS.
