Vitalik Buterin and his team did not create Ethereum just to become another Bitcoin. Ethereum was created first and foremost on the basis of what Bitcoin is not. Vitalik knows Bitcoin very well and he thought that he could create something out of its inspiration, something which could be used in some other things which were clearly not in Satoshi's mind when he created Bitcoin.
