I do. Software isn't my progeny or legacy. It is the tools in my workshop. If I can use one tool to do the work of five, I'll gladly downsize to declutter and simply my life.
Finding self-worth in the longevity of tools is an emotional anti-pattern.
I gather maybe the Google advancement structure discourages doing nothing and generally being stable when it makes sense, in which case there could be plenty of improvement to be had all around.
Granted, I have no inside information. That just fits the externally observable information and the tiny amount of corporate politics that occasionally makes its way public.
Google has had something like...seven(?) chat and chat-like projects, and each new iteration of "let's kill the most popular chat product we have" seems to result in several new chat-like things, most of which fail and many of which are weirdly complicated and/or confusingly branded/messaged.
I don't mean to be short, but...based on what evidence?
