".. in the modern world", "... younger generation". Maybe you're just getting old? If "OOP had it right all along" there wouldn't be a revival of interest in FP. OOP encourages mutable state and the bigger your programme the harder it is to keep track of it. Rampant mutable state also makes concurrency difficult and concurrency is now more important than it was due to multi-core hardware.
