I think that bitcoin forking is useless, why do we need another bitcoin? These forks won't bring anything good for us

If i am not wrong , these all FORKS are having something very similar , they are changing Algo of Bitcoin so that GPU/CPU ( easy ) reachable coin for every machine. Not just Asic.
Proof Of Work
But Forking seems odd in this all, they can make something Unique too if they just want to build a coin. Or may be C or C++ students just want to test there skills if they can make something like Bitcoin as project or not.
