Vibe coding is scary real!

A Cisco executive shares how vibe coding transformed a 15-year-old, 500,000-line proprietary 5G network function into a modern Golang microservices architecture using gRPC in just one week — a project that would have taken over a year traditionally. The code was reduced to 106,000 lines and passed initial smoke tests. The exec went from skeptic to believer, predicting AI-assisted coding will become the default way software is developed within 6–12 months, while acknowledging extensive validation is still required before production release.
