Not Another Workflow Builder

LangChain explains why they haven't built a visual workflow builder despite frequent requests. They argue that no-code workflow builders are getting squeezed from both directions: simple tasks are better solved by AI agents that just need prompts and tools, while complex tasks require actual code that's becoming more accessible through AI code generation. Rather than building another workflow tool, LangChain believes the future lies in making it easier to create reliable AI agents without coding for simple tasks, and improving AI's ability to generate code for complex workflows.
