"Don't Pursue Archives" - Seeking Support on Advice I was Offered

Hello all!

I am beginning my MLIS in the fall with the great fortune of having received a teaching assistantship offer that will cover most of my tuition as well as a stipend that can cover my rent that is in library services. My intentions, at least initially, were to pursue becoming a digital archivist, preferably within a university setting. I am also in the unique position of having an interview for a different, better-paying assistantship that is in digital repository services/digital librarianship, albeit I have not done the interview yet (wish me luck!).

I was speaking with the special collections archivist at my university (where I'm earning my first MA), and she told me that, with my 2 and a half years of teaching under my belt/my MA and the potential to earn even more teaching experience if I accept the first offer, I should...not pursue archives at all, but instead pivot towards academic librarianship because I enjoy teaching, have the experience and could, quote, "actually get a job in it compared to how bad the archives market is." This is advice I also received on a different subreddit when I'd been asking about something else, so obviously I've paused to reflect and it has left me a little torn.

I still accepted the interview invite and will do it whenever I'm scheduled, but part of the reason I pivoted to librarianship at all was because I wanted to be in a university setting and get to teach/work with students and faculty while working on my own projects (aka, digital archives) without dealing with the dumpster fire of a job market that my humanities field post-PhD outlook would have been.

All that is to say: is she right? How bad is it (be honest)? Would taking a lower-paying assistantship, since it's more directly relevant, be the better 'move' if I pivot?
