I had failed to make a multiplayer computer game with traditional approach and realized firebase solved all my concurrency and push problems in a much neater way, and the security language didnt compromise too much expressivity unlike many other SaaS dbs. So i saw it solved a real problem in a simple way, way better with better ergonomics than i could do myself

I found out about it just by reading hacknews and noticed it seemed to be posting a lot and well.
