It’s a very interesting interview. Jeff Vogel is a pretty pragmatic person and has been able to stay afloat and indie making very niche games for 30 years.
I do find the interviewer a bit naive, but overall I found this very interesting.
I found the interviewer really naive. 
However, I did quite enjoy the interview. I think overall, the questions the interviewer asked were pretty good.
Honestly, Jeff Vogel is probably the only person I’ve ever looked up to. I appreciate his perspective a lot, and his GDC talk, which they mention briefly in the interview, had a pretty big influence on how I designed my current strategy and process.
Granted, I haven’t been successful yet. But, as he points out, it’s hard! Most people fail. But I think this is okay for me right now, since I’m currently optimizing for something else over the long term.
