I understand that I don't have full expertise and I always listen to our devs, however it really helps me when I understand what they are talking about and I listen to them.
Also since I can quickly make some stuff from code I can google on the web, I'm much more productive than the average Joe when I got some repetitive task: make some excel function to deal with ugly data parsing, automate some data entry with auto-it or python+selenium, make some basic sql queries when I need a quick report...
On the other hand half of the people I work with can't write a simple vlookup formula or getting confused when it doesn't match a text to number, despite having excel in their CV.
When a person knows how computer magic works is only a benefit in my opinion and would be a strong bonus point for a job candidate.
