Senior engineers gain 30% productivity from AI tools, but juniors create technical debt; industry refuses to hire entry-level talent while betting on AI to fill the gap

Senior engineers with 5+ years of experience ship 30% faster using AI tools like Copilot, Cursor, or Claude and catch hallucinations instantly. Junior developers using the same tools also ship faster but create technical debt requiring months to unwind because they cannot distinguish between good and bad suggestions.

Big Tech hiring has collapsed: only 7% of new hires are recent graduates (down 50% from pre-pandemic levels), 74% of developers cannot find jobs despite claims of talent shortage, and entry-level positions require 2–5 years of experience. Trump's $100,000 per H-1B visa fee closed the foreign worker bypass strategy companies relied on for years.

Energy and compute constraints limit AI's ability to scale: a single ChatGPT query uses 0.3–0.43 watt-hours versus Google's 0.04 (roughly 10× more), and data centers already consume 4.4% of US electricity, heading toward 12% by 2028. H100 GPU waitlists stretch 6 months, and 92% of advanced chips come from TSMC in Taiwan, creating a single point of failure.

Three companies in the author's network attempted to replace expertise with AI alone; all three entered crisis within 6–18 months and are now hiring senior engineers at 150% of market rate to fix technical debt and security breaches.
