How can you guys code 9hrs everyday? Doesnt it get hectic?

Why are devs at google making it hard for android developers? They release libraries so frequently and completely overhaul everything. It was fine till a limit. Now again they are releasing jetpack compose which is a completely new thing. I don't have problem learning new things but the rate at which they release new stuff is far swift than other frameworks. For example they release a new dependency injection hilt while recruiters still look for dagger 2. Android is just getting overwhelming. What are your thoughts?

Whats the best way to implement comment system in android. I am using firebase for backend. I came across only a single article on medium for this but that too is cumbersome.
