World domination of course, but until we achieve that our goals are:
A reliable OS which never hangs (of course until the hardware fails). Whichever program crashes, the OS should never hang or go unresponsive.
Very safe (safe in the sense which is free from buffer overflows, heap overflows, exploits etc.)
Drivers and programs being able to be verifiable/tested. Even the Kernel should be verifiable at a later stage (maybe using TALx86)
The LINUX of tomorrow.
