Unit tests are most useful for parts of code that have complexity to them - like engineering math or geometry calculations etc. Things that you need to really make sure produces the right answers.

I never understood people making unit tests for button clicks calling whatever function. Those seem like just pointless churn unit tests that don't really add any value.

Unit tests are good - but be smart about it and don't be overboard. It's like programmers that add a comment to EVERY line of code - it's really not necessary and clean, well-written code doesn't need that on ever line. Only on the non-obvious bits.
