How does it know what scene you want? If you walk in to a room and want to watch TV, you might want the lights to be dimmer than if you're going to read a book, for example.

For selecting an album or movie to play, it's easier to use a menu on a screen than to try to explain it verbally.

How? I can put on my best Captain Picard voice and say 'Computer, play the album Insomniac by Green Day' much faster and easier than I could pick up the remote, turn on the media player, scroll to music, scroll to G, find Green Day, scroll to Insomniac, and press play.

I've got Amazon devices (bought before I knew how bad both they and Amazon are), and they're not great. Even with them, I can walk in to my living room in the night with my hands full and tell them to turn my chosen lights on, set the brightness and colour, start playing my chosen music, or turn the TV on and start playing certain media, all while I'm walking to my seat.

The only media that I can't play is what I haven't set up to use with Alexa yet, but that would be the same for any automation.

When I get around to it, I'm going to add either Plex or Jellyfin to my voice control setup, and hopefully be able to play anything from my library in the same way :)
