Google changed how software works – MCP + A2A changes forever

Hey, I'm back. There's another new AI thing to talk about, uh, of course. So, what happened today was that Google announced A2A, agent to agent protocol and it connects to something I've been obsessing over lately, which is MMP or model context protocol. They both are protocols. I'll explain what I mean. First, let me back up. I wrote a deep dive on substack about model context protocol, totally free. It's fundamentally like don't have to go read it. I'll explain it right here. It's a fascinating shift in how AI systems work with tools because before for 70 years we would program exactly what we wanted AI to do. And now we let AI decide what to do. And so what we mean by that is that instead of programming every step in a workflow, model context protocol allows us to describe tools. And let's AI figure out how to use those tools. So think about that instead of writing specific instructions like if this happens use this tool, you're just saying, here are all the tools available and you figure it out. You reason, you figure out what you need to do. It's like the difference between giving someone step-by-step instructions versus just handing them a map. A to A to come back to the news today, takes that to a new level. So instead of agents just picking their tool
