I can, but I don't want to. Is that unreasonable?
I've quite enjoyed adding automation to my home. My outdoor lights slowly brighten as it gets dark outside - not by a timer, but by checking the actual times of sunrise / sunset as well as how cloudy it is, which might make it darker sooner. I can check my phone to ensure my doors are locked and my garage door is closed and my yard lights are off. I get a notification when the washer / dryer are finished. When I'm done working, I say a simple command and my office lights fade as my desktop locks.
I can set timers and check my laundry and then wait the extra 5 minutes it adjusted to finish. I can log out and hit the switch on the way out. I can get up every evening and turn on the outside lights and then turn them off in the morning. I can adjust my thermostat once I get up instead of 15 minutes before. But I don't really want to.
As a programmer, having an API for my home has been tons of fun. Controlling some of that API with my voice has been as well.
That said, I've made sure everything still works when my pi is down, because sometimes a light switch is, you know, simpler.
