I really like your sentiment, but I'm not sure if "OO was invented for X" or "FP was invented for Y" is right. They are abstract paradigms that were created with very little connection to their underling usage at the time (FP in particular stems from a mathematical background, but most of OO as well). Rather I would say more then "OO is more suitable for GUI" and "FP is more suitable for compilers" (though I'm not sure if I agree with that)
