"So the secret of open source is the license, and this is a thing that I didn’t really appreciate until fairly recently. Licensing is important because of copyright. And I think a lot of people don’t realize that copyright happens automatically by default, whether you do anything or not. So that was a thing, in the course of us planning this episode that I had no idea about, I thought that I thought that you copyright your work, you had to actively go through some kind of legal process to instate that. But apparently that’s not the case. Can you help demystify that?"
