Prompt injection appears in 73% of production AI deployments. Firewalls can't see it. Antivirus can't catch it. The attack surface just changed permanently. - hackernoon.com/why-ai-securit… #softwareengineering #artificialintelligence

@hackernoon We don’t talk about this enough.

Wrote this because every "AI agent" post is either a GPT wrapper demo or pure theory. 7 agents running real marketing ops for ecommerce brands spending real money. Hardest part? Not building the smartest agent, it was getting them to NOT talk over each other.
