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)_/¯

In recent months, major Bitcoin mining companies have started to swap out some of their mining equipment in favor of rigs used to run and train AI systems. These companies believe that AI training could provide a safer and more consistent source of revenue than the volatile crypto industry.

Morgan reported on June 24.
