Why the flying fuck would anyone want a home automation system that isn't voice controlled?

I don't want a voice assistant controlled by Google, Amazon, or Apple... but I value it so much I'm willing to compromise until there's a better option. This is a huge step in the right direction.

I setup my voice activated lights when my daughter was an infant. It was great being able to sit in a chair and rock her to sleep and be able to say "Google, it's nap time" and have the lights properly adjust, and the fan turn on. I also use it in my office when I have a video call to adjust the lights so my camera looks better. I can also lock my door, adjust my HVAC, and play music without needing to stop doing whatever I'm busy with.
