theis is at least the second comment saying that you can prove usability.
yes you can, but you are only proving usability for the users skill set that you test with.
you can get _very_ different answers to usability questions from users that have never seen a computer before (but you can't repeat the test with those users, because they now have the experiance of your first test) then if you test with people who have used windows for years then if you test with people who have used Macs for years.
which set of results is 'more valid' is definantly arguable.

And also by testing monkeys and cats. What's your point? Test the target group of people you want
to sell your OS to.

No answer is right. You test all the groups of people that you want to be able to successfully use
the UI. This makes the whole thing much more expensive, but that's what you get when you want a
UI which is useful for grandmas, astronauts and monkeys.
Back in the real world, businesses decide narrow segments where they want to market and sell their
software, and test only those, trading off the cost of developing for each segment with potential
return.
