Let's not forget that nowadays each pointers takes 8 bytes (64 bits) instead of 4 bytes like it was the case on 32 bits systems most of us grew up using, and often have the numbers for in mind. Executables are bigger because of that, and so are their stack and heap (probably not twice as big but probably not too far from that!).
