Each time, a moment came when the existing software and infrastructure became too constraining, forcing everything to be rebuilt to accommodate the new paradigm. We are at this juncture once again, but this time it is being pushed by AI agents.While the leading companies have been busy over the past few years programming agents to use software in the manner of a typical person (clicking buttons, filling out forms), the top players have decided to build the software for agents. This is more significant than most understand.Building for Agents, Not HumansImagine agents as self-driving cars operating on infrastructure built for human drivers, with stoplights, painted lanes and other rules designed for people. That creates obvious inefficiencies. The smarter approach is to redesign the infrastructure to match what agents do best.Yann LeCun, former head of Meta AI and a luminary in this space, succinctly described the approach: Agents will communicate effectively with each other without pretending to click buttons. That is not a hypothesis but rather a technical inevitability. It is already happening.MORE FOR YOUThe New Agentic Infrastructure LayerAnthropic, among others, foresaw the future and created the Model Context Protocol in advance, offering developers a standardized protocol for connecting AI systems to various tools...
