You can ask me what I think about inflation but that wouldn't make me an economist, would it?
So you admit you don't really know much about the matter, but consider your opinion qualified by virtue of somebody asking you for your opinion?
Yes, I admit that I don't know much about OSS. But I did not state that I have a qualified opinion. In fact, I answered "Don't know/no opinion" on those questions.
The reason I posted my reply was to indicate that there must be some people worried about the situation, or it wouldn't have appeared in a survey from a very large, frequently mentioned on HN, tech company.

No, but you could relay the fact that somewhere there are people who are apparently concerned enough about inflation to ask you about it.
It's a strange question, to ask if OSS will still be around that far in the future. It (albeit without the name) has been around longer than proprietary software. Did your survey ask if proprietary software would still be around in 20 years? I think it should have.
I think there might be.
I'm not involved in OSS circles, and don't really pay attention to the issues much beyond what I see on HN, but recently in a survey I completed for a tech company there were a number of questions asking my opinion on whether OSS is still a sustainable model, and if I believed it would be around 5, 10, 15, 20 years in the future.
