I've been thinking about this lately too. I think we're going to see the rise of Extremely Personal Software, software that barely makes any sense outside of someone's personal context. I think there is going to be _so_ much software written for an audience of 1-10 people in the next year. I've had Claude create so much tooling for me and a small number of others in the last few months. A DnD schedule app; a spoiler-free formula e news checker; a single-use voting site for a climbing co-op; tools to access other tools that I don't like using by hand; just absolutely tons of stuff that would never have made any sense to spend time on before. It's a new world. https://redfloatplane.lol/blog/14-releasing-software-now/
I think people overestimate the general population's ability and interest in vibe coding. Open source tools are still a small niche. Vibe code customized apps are an even bigger niche.
