Side-comment of something this made me think of (again): tech builds too much for tech. I've lived in the Bay before, so I know why this happens. When you're there, everyone around you is in tech, your girlfriend is in tech, you go to parties and everyone invariably ends up talking about work, which is tech. Your frustrations are with tech tools and so are your peers', so you're constantly thinking about tech solutions applicable to tech's problems.
This seems very much marketed to SF people doing SF things ("Cursor, Gmail, Slack, even your terminal"). I wonder how much effort has gone into making this work with code editors or the terminal, even though I doubt this would a big use-case for this software if it ever became generally popular. I'd imagine the market here is much larger in education, journalism, film, accessibility, even government. Those are much more exciting demos.
