Yeah I’m totally fine with him spending his money on whatever hobby he likes, but the message is just strange, this and the other message that “he wants [GPUs] to be used for research and discovery”. And donating the $3k prize money to his high school to advance math and science education after burning $2m… It’s obviously still a nice thing, but why would you even mention it…

That said, maybe he felt pressured to give the reporter more than “I was just having fun”.
