Fascinating conversation with an old friend this week about the world of API "auto-discovery" and documentation. Basically, systems that allow software to negotiate an interface with other software, within certain constraints.
It's AI adjacent these days, because those systems are what would probably have to power an "Ask your phone to do something, and it'll figure out how" style feature. LLMs might be involved in natural language portions, but the task-work would be done by discoverable APIs.
