Something like this could be helpful but nobody should be willing to give up their families privacy and autonomy to a cloud solution ran by Google that could disappear at any point in the future. This is the kind of thing you want to have some level of control over and the ability to keep it going as long as it’s useful vs. rely on a corporation that has made its money datamining everything we do to sell advertising. Either they’ll eventually abandon it or worse case figure out how to load it with surveillance to sell targeted ads.
