Only a waste of time in the sense that worrying about the end of fossil fuels, or the overcrowding of the Earth, or the risk of having our entire species on a single rock is worth worrying about. I'm not going to lose any sleep over it, but I hope someone's thinking about it. And it makes a lot more sense that some of the most powerful men in the world (Gates, Hawking, Musk) are worrying about it since it's on the decades-out timeframe as opposed to months or years. AI researchers are probably more like me, wondering what they're going to get for lunch tomorrow and how to optimize the next algorithm.
