Yes, but now I don't have to get up to switch my light off.
Of course not.
I have my hands full cooking. Is asking "Alexa, set a potato timer for 12 minutes" any lazier than stopping my stirring the sauce, wiping my hands, picking up the timer and punching buttons on it to set a timer? I can keep going about my tasks and have the Alexa device help. Likewise, "Alexa, turn on dinner table" or "Alexa, announce 'Everybody get down here, dinner is ready'" These are little conveniences that keep a busy process going smoothly.
Could I live without them, sure. But I could live without electric lights and plumbing too. But why would I when they exist and are available at a reasonable expense?
Luddites, the lot of you.
