+====== I Want to Start Learning AI: Complete Roadmap (2026) ======
+**AI is the single most valuable skill of this decade. But the field is huge — machine learning, deep learning, prompt engineering, AI ethics, agents, MLOps. Where do you actually start? This guide gives you a 12-week roadmap from "I know nothing" to "I can build useful AI tools" — with free resources, real projects, and an honest path to a paying job.**
+===== Quick Answer =====
+  * **No coding background?** Start with **prompt engineering** + **using AI tools well** — high value, no-code path. 4-6 weeks.
+  * **Some coding (Python basics)?** Start with **practical machine learning** via Kaggle + fast.ai. 12 weeks to first project.
+  * **Engineer / CS graduate?** Skip basics. Go straight to **deep learning** (PyTorch/TensorFlow) + LLM applications. 16 weeks.
+  * **Free essentials**: Kaggle Learn, fast.ai, Hugging Face NLP, Andrew Ng's Coursera (audit free), DeepLearning.AI Short Courses.
+  * **Daily commitment**: 1 hour for casual learners, 3-4 hours for career switchers.
+  * **First project ASAP**: theory without project = forgotten in 30 days.

+===== FAQs =====
+==== Do I need a degree to get an AI job? ====
+Helpful but not mandatory. Strong portfolio + Kaggle competitions > generic certificate. Top companies care about what you can build.
+==== Can I learn AI in Hindi? ====
+Yes — major Hindi YouTube channels: **Krish Naik** (Hindi+English), **CodeBasics**, **The AI Bug**. Hugging Face has community resources in 10+ Indian languages.
+==== Best degree for AI career? ====
+**B.Tech CS / IT** + master's (M.Tech / MS) ideal but not required. Pure math + statistics also strong. Many top engineers come from physics, electronics, mechanical.
+==== How long until I get a job? ====
+Track A — 3-6 months. Track B — 9-18 months (depending on prior coding experience). Most people overestimate by 30%.
+==== Free GPU for projects? ====
+**Google Colab** (free + paid Pro), **Kaggle Notebooks** (free 30 hrs/week T4 GPU), **Hugging Face Spaces** (free CPU), **Lambda Labs** (paid but cheap).
+==== Should I start with PyTorch or TensorFlow? ====
+**PyTorch** in 2026 — 80%+ industry + research. TensorFlow for legacy code or Google Cloud-heavy environments.
+==== Will AI take my job? ====
+AI **augments most jobs**, replaces some. Routine, repetitive, language-heavy jobs are most at risk. **Learning AI itself** is the best hedge.
+==== Hardware needed? ====
+Beginner: any laptop. Intermediate: Nvidia GPU helpful (RTX 3060+). Advanced: cloud (AWS/Colab Pro).
+==== Best YouTube channels? ====
+**Andrej Karpathy** (best world-class teacher), **Two Minute Papers** (research news), **Krish Naik** (Hindi+English), **3Blue1Brown** (math intuition), **Yannic Kilcher** (papers).
+==== When to specialise? ====
+After 3-6 months of broad exposure. By month 6, you'll know what excites you (NLP / vision / recommendation systems / agents).
