I think AI makes personal software possible in a way that it wasn't before. Without LLMs, I would have never had the time to build a component library at all and would have probably used 8bitcn (looks awesome btw) and added the neo-brutalist shadows I wanted.
However, despite my gripes with ShadCN for Astro being minor (lots of deps + required client:load template directive), just small friction points are enough that I'm willing to quickly build my own project. AI makes it barely any work, especially when I lower the variance using parallelization.
