> I don't want to trust Zulip to survive 15 years.

You don't need to, we have an official tool that generates an HTML archive: https://github.com/zulip/zulip_archive. We recently adopted it from the great folks at the Lean Prover community, but we have plans to make it a lot nicer over the next couple months.

That said, one of Zulip's central technical design principles is to invest in making a codebase that is easy to understand, well-documented, and readable, with the goal of ensuring Zulip is able to thrive for the next 15 years and beyond.

I've been meaning to write a series of blog posts on the topic, but check out the 150K words of mostly Zulip developer-facing documentation on our ReadTheDocs:
