Cisco Gave a 27-Year-Old Unlimited AI Tokens to Rewrite 98% of Its Legacy Code

“Cisco just handed a 27-year-old unlimited AI tokens and told him to rewrite 98% of the company’s code. He has four weeks to show it isn’t insane.”

The Story

Cisco president Jeetu Patel plucked 27-year-old former startup founder Padmanabhan Krishnamurthy (buried five levels down after an acquisition) and gave him unlimited AI tokens plus a two-to-three-person team to rewrite 98% of the company’s decades-old code in 24 months. He has four weeks to prove the approach; Patel told him to “go nuts.” The goal includes migrating to memory-safe languages.

Why It Matters

Work, institutions, and identity—old-office Cisco lore colliding with a Gen-Z catalyst and unbounded AI. Builder utility (how companies actually try to eat their own legacy) plus future-shock of “two people + tokens vs. 40 years of code.
