What is the most useful programming language to know (if any) in fields of mammalian cell culture and/or stem cell research?

Context: A.S. in biotech, B.S. in biology, few years of experience doing gene editing research with stem cells and doing a lot of CHO cell culture at a bioprocess development lab.

I recently quit my job because I hated it. While I look for a new one (likely in the same general realm of cell culture/molecular stuff), I was thinking it might be useful to pick up a language. At my previous job, there were times when I felt it would have been useful if I knew Visual Basic (mostly for excel macros). But I'm wondering if there's some most-desired language for a benchtop monkey to know, if at all.
