with jev, it's nice to see builder energy back on X, reminiscent of the early days of building with LLMs (back when gpt_index/llama_index/langchain first started) before jev, most of the 2026 AI demo hype has revolved around the end-to-end capabilities of frontier models. The art of how to build something started taking a backseat to having agents automate as much work as possible. jev is a lego block. it puts the joy of building back in the hands of humans. it forces you to think about how to build something as a system, instead of one-shotting a prompt through astra/fable.
