I'm not saying it's impossible, but it's just not worth learning steno if you mainly do programming. It will be complicated, require complicated chords, require you to constantly add new words and remember what you saved them as, simple chords (short cuts) like C^n turn into complicated ones. It's just not that optimized for programming.

I think this will be better answered by someone who has crossed that bridge than you simply jumping to that conclusion with no experience or data to back up your claim.
