Yes, I have such thoughts. I'm building something constantly, have a history of attempting different projects, some of them got into startups fueled purely by passion and lasted for years, but didn't attract investments. Currently I'm working on MASS - Modular AI Scheduling System, basically it's a scheduler and package manager for AI-native applications/services. As I see a huge part of future AI as dedicated small fine-tuned models, local to user and on-site programs and services. But it's another story :)
