Most companies with just competent ability to build a software product have a moat. Somehow most companies suck at it despite years of being in this business.

Most companies with just competent ability to build a software product have a moat. Somehow most companies suck at it despite years of being in this business. Dozens of clones of common products for web search to chat to ???, yet how often do they just break at that one thing you absolutely need? The product is a usually an OKish 80/20 implementation of something, but the missing last 20% is often the differentiating polish. For ChatGPT* that polish is the extensive grunt work RLHF to really fine tune these models to be relatively helpful. It’s the extensive backend data prep work, tokenizers, orchestrating a massive cloud to train LLMs, and creating a good enough user experience that it “just works”. Simple made easy is never easy :)
