Instead of creating the weekly/monthly/latest G-powered chat product, why doesn't Google go all-in to leverage something like the matrix protocol? Gmail is so successful and it leverages the universal, decentralized email protocols. For non-techy users its clear the value platforms like gmail bring. Yet, there are so many tech-savvy users who COULD be managing their own mail/smtp servers and infrastructure but instead CHOOSE to still use gmail. I think there is an opportunity here for google on chat, and it does not involve constantly designing a new chat product almost every frickin' week. I firmly believe that google could build a single/final chat product but leverage an open (and distributed) protocol like matrix...and still win mind-share, market-share, make enough money on ads (displayed in the chat product), allow for 3rd-party integrations, etc. But, hey, whatever.
