Laughable, and it's obvious that you didn't think well about it before making that statement. There's more to mining than mere hashing to "win the lottery" for rewards. There's a particular dynamic between mining difficulty, the price speculation of Bitcoin, the demand for blocks, and so on. To say that it's "becoming a thing of the past" is simply WRONG. In fact, the way HashCash is utilized in Bitcoin, it's actually a thing of the future. ¯\_(ツ)_/¯
