Standards like the LAMP Stack, GitHub and Stack Overflow did such a good job of popularizing open source that they practically made it obsolete. Just like “mobile phones” are simply becoming “phones”, “open source software” is simply becoming “software”. This is an incredible win for open source. But it comes with new challenges: how to actually manage demand and workflows, how to encourage contributions, and how to build antifragile ecosystems. We may not feel the burden yet, but winter is coming. In a post open source world, these are problems we’ll all have to contend with.
