Alexa doesn't solve 99.9% of housework. I want a robot to make me meals and clean the house. Checking the temperature and listening to music isn't revolutionary.
That’s the general problem with smarthome stuff. Turning lights on and off is not actually high on my list of tasks I don’t want to do. Those that are like laundry are partly aided by specialized robots. Others like the lawn, shoveling, cleaning, etc. are addressed by either paying people or doing them myself.
