Honestly, the negativity in the comments so far has me flummoxed. What I see is a person, in a development role, posting about how they have been made to feel inadequate or unsuitable for their role, because they don't know things that aren't necessary for said role.

If someone is succeeding, who cares whether they know Awk? If someone is doing the job and getting paid, who is anyone to make them feel inadequate, call them whiny, etc. What do we gain, both as people and as a community, for snubbing people who post things like this?

Note that I didn't mention whether those things would make them better at their role. They probably would, but it matters less than the bulk of the comments seem to think.
