What do you class a "substantial program"?
For me it is something I can describe in a single casual prompt.
For example I wrote a fully working version of https://tools.nicklothian.com/llm_comparator.html in a single prompt. I refined it and added features with more prompts, but it worked from the start.
Good question. No strict line, and it's always going to be subjective and a little bit silly to categorize, but when I'm debating this argument I'm thinking: a product that does not exist today (obviously many parts of even a novel product will be completely derivative, and that's fine), with multiple views, controllers, and models, and a non-trivial amount of domain-specific business logic. Likely 50k+ lines of code, but obviously that's very hand-wavy and not how I'd differentiate.
Think: SaaS application that solves some domain specific problem in corporate accounting, versus "in-browser speadsheet", or "first-person shooter video game with AI, multi-player support, editable levels, networking and high-resolution 3D graphics" vs "flappy bird clone".
When you're working on a product of this size, you're probably solving problems like the ones cited by simonw multiple times a week, if not daily.
