A2A Is Not a Feature. It Is a High-Stakes System
We are entering a phase where AI systems no longer operate only in a human-to-machine loop, but increasingly in agent-to-agent (A2A) interactions. This is not a product upgrade. It is a structural shift. When autonomous systems negotiate, optimize, coordinate, or escalate without direct human mediation, the system boundary changes. Responsibility diffuses. Latency shrinks. Error propagation accelerates. In low-stakes environments, this is manageable. In high-stakes domains , it is not. What “High-Stakes” Means Here High-stakes systems are not defined by intent, but by consequence.
