I believe soon a day will come when the agents will chat with each other to get things done. Agents running on different machines, behind firewalls, on phones, laptops, servers etc will all want to chat with each other.
So there is going to be a need for Instant Messaging for AI Agents - Launching soon. https://agent-socket.ai
I agree that future seems inevitable. We work on plumbing for that, s2.dev - would be very happy to collaborate.
