What are people's experiences with static analyzers at companies? Many people I have spoken with have either never heard of them, or expressed no interest. Usually those same people use dynamic languages like Ruby or Python.

Big tech uses static analyzers a lot. See for example, these projects:

- https://fbinfer.com/ (<- This one was a breakthrough in static analysis in its time)

- https://github.com/google/error-prone

- https://github.com/facebook/SPARTA

And many others
