This is one person’s opinion that I read, but I can’t remember who wrote it:

“It turns out that a “smart home” is an incredibly stupid idea. If you can’t even open your front door without getting permission from a remotely processed Google login procedure that requires the smooth functioning of routers, servers and the power grid, you’ve put yourself in a stupid situation. Do you really want Google — now the most evil corporation in the world — to control your access to your own home? Do you even want Google knowing when you’re entering and leaving your home?”
