Perhaps if it was something to be rolled out worldwide. As it is, with most of the world using “something else”, this would only be for US users. Which is why, rather than a worldwide ad blitz, Google’s ONLY advertising in the US and ONLY via an ad campaign focused on ONE of that countries’ cities.
It’ll eventually run out of steam as Google’s not making as much as they used to and are already axing many internal projects. Eventually, someone inside will ask, “Do we actually think that spending this money will provide any results? Like, what’s the profit motive.” There will be blank stares and >blip< another messaging service bites the dust!
