What I’m saying is that to experience the improvement of being able to turn on your lights by talking to your Google Home vs. simply walking over to the light switch and toggling it’s position, you had to buy a whole bunch of smart light bulbs, plus the Google Home devices. So, there is a large expenditure of money and time just to get everything installed. But also, now, being able to turn your lights on by speaking out loud depends on an incredibly complex stack of technologies. There are two entire operating systems, networking stacks, etc. that all have to work in order for you to continue accruing this benefit.
That might be worth it to you, but it seems like chasing extremely marginal returns to me.
