Ask HN: Is it worth it for me to learn Go or Rust as a Data Engineer?

I've been working as a data engineer now for about 4 years professionally, exclusively in Python and the various flavors of SQL. I also have some experience in C, C++, C#, and Java from university. I have seen the occasional job post that mentions Go or Rust as something that would be nice to have. I have yet to encounter any projects in my career either in-house or otherwise that uses these languages. Would it be worth my time to learn them on the side or to try and propose our next tool, pipeline, etc. be written in one of them?
