Hmm.
Interview of an indie game developer?
Very long and still ongoing development of the game?
In-depth Q&A?
Not a text interview, but an audio interview?
Longish interview duration?
Didn’t search for it, it found its way here by itself: a two parts Dwarf Fortress creator interview recommended today by YouTube.

(a lot of topics are covered, a lot, look at the video description for an overview of the content and shortcuts to each topic)
Which reminded me of the 2019-02-19 Space Game Junkie Podcast featuring Alex:

It’s worth listening to even today! On the other hand, the gameplay footage is, uh, not stellar, so I would say don’t bother watching while you are listening.
So, if we put the two together - (1) a community run interview with curated sensible in-depth questions and one good interviewer, (2) Alex willing to participate - then we might obtain a holy grail up to date Starsector interview. :) The Dwarf Fortress interviews linked above set a high standard that should be attainable. And I think the right moment for such an interview could be a few weeks after next release, after the early feedback / bug fixing rush.
