+> - We all `start with scripting`, no matter the language, it’s the first step. `Simple/complex instructions, written line by line`, to get something done
+> - Then comes `machine learning`. At this stage, we’re not reinventing the math, we’re `leveraging powerful packages built on deep statistical and mathematical foundations.` These tools let us `automate smarter processes, like reviewing claims with predictive analytics. You’re not just coding anymore; you’re building systems that learn and adapt.`
+> - `LLMs`. This is what most people mean when they say `AI.` Think of `yourself as the architect, and the LLM as your strategic engine. You can plug into it via an API, a key, or through integrated services. It’s not just about automation, it’s about reasoning, understanding, and generating human-like responses.`
+> - And finally, `agents`. These are LLMs with the `ability to act`. They don’t just respond, `they take initiative. They can create code, trigger workflows, make decisions, interact with tools, with other agents. It’s where intelligence meets execution`

+> [!NOTE]
 > A landing zone is a general `cloud framework that sets up the core structure for all workloads`. Each use case (like an app, data pipeline, or API) then builds on top of this framework, using the `same environments (Dev → Test → UAT → Prod) and CI/CD pipelines to move code safely into production.` It’s general by design, but `applied per use case.`
