Why do people ever switch chat apps? Besides shutdowns, it's because the new app does something the old one doesn't. Signal's pitch was easy encrypted messaging, but now there are apps that fill that slot, even Facebook Messenger has e2e encrypted chat, so there's not a lot of reason for Google to invest there. Google Duo has succeeded as an app known for making video calls, which is as much a marketing/positioning achievement as it is a technical one. There are lots of people declaring they will use a Google product in this thread, but of course no one is going to use a nonexistent product that people imagine as a clone of what already exists. Unless Google finds an "in", they're not going to get anywhere, even with whatever perfect app HN imagines.
