I totally agree.
I learned assembly, totally useless now.
I learned Delphi, it got replaced with c#.
I learned c/c++, 0x is the new thing now.
I learned win32, it probably will be replaced soon.
... Directx 9 -> useless now because of dx 11
same for opengl 2.0
It's getting anoying... By the time you master something, that you are really good at it,
it become useless/depreciated/fallen deep into the abyss of another dimention..........
