The Devil Was Never in the Details: Code, AI, and the Rise of the Deep Generalist
summary
Argues that the seams between services—not individual platforms—determine success, and that AI magnifies the need for cross-domain practitioners who stitch systems together. Cites migration from LAMP to Kubernetes, infrastructure-as-code risks (one Terraform file can screw up a million servers), and that 51% use AI daily. Compares vector versus graph stores for RAG, lists Bedrock, Lambda, Step Functions, Dynamo, Elastic Search and agent-core tradeoffs, notes voice agents at scale are brittle and LLMs hallucinate and can delete prod DBs unless checked.
