I'm picking on rust here because it's no secret it has a long history of having some very... enthusiastic users. But my broader point is that tools are just tools. They're not our identity, a mark of our wisdom, or a moral choice. Other people have different perspectives, tastes, and skills - and they may prefer different tools to us.

You can set multiple alarms with different bedtimes and wakeup times, which is really handy if your schedule is all over the place or you want to allow yourself to sleep in more on certain days. My only real complaint so far is that the sunrise feature isn't quite as strong as I want it to be. The Dreamie's sunrise goes from a warm glow to a bright blue-white, but it never gets big enough to wash over me in the way I expect a sunrise alarm to. Having the light on is helpful for orienting yourself when you're groggy and half-asleep, but it doesn't feel like it's having much effect on my actual wakeup process.
