It might be neat to voice activate a mood with lights, music, etc. but the amount of effort to set that up and maintain all of that is literally 100x the effort

It might be neat to voice activate a mood with lights, music, etc. but the amount of effort to set that up and maintain all of that is literally 100x the effort I'd spend flipping a couple switches and turning on a playlist on a speaker. Literally 60 seconds to do it manually (assuming you know/have setup a playlist). The only "smart" devices I have are for a room where you want a switch for a lamp but there isn't a switched outlet. Add a smart plug and a physical switch, done. No hub, no scripts, no automation. Its cheaper than buying smart bulbs which usually require some manufacturer's hub/app/nonsense.
