I'd argue that AI isn’t just the future of networking, it’s the present. We’re already seeing production systems that let you interact with a network in plain English, across tools and vendors, without logging into a dozen dashboards. Read here:

Behold, the Cisco FastHub 108T from 1997 - when 100Mbps shared bandwidth was cutting-edge and we lived without VLANs or auto-negotiation. Almost 30 years later, this single collision domain relic really shows how spoiled we've become with modern networking. (Yes, that's an OUI transceiver on top 🙂)
