I think the biggest change in the past year (vs. 15 years ago) is the ability to interface with products like Amazon Echo and Google Home. It's very convenient

I think the biggest change in the past year (vs. 15 years ago) is the ability to interface with products like Amazon Echo and Google Home. It's very convenient to be able to control lights from anywhere in the room by issuing a voice command. Not just turn them on and off but also dim, change colours, etc. Granted this is from the perspective of living in an apartment :)
