Daniel Priestley joins The Diary Of A CEO to argue that AI will fundamentally invert which professions command the highest pay. As AI commoditizes knowledge work, physical trades like plumbing will become relatively more valuable because they require embodied skills that AI cannot replicate. He predicts that within a few years, plumbers will regularly earn more than lawyers.
For decades, blue-collar work has been devalued relative to white-collar professions. AI is reversing this. Knowledge work (legal research, financial analysis, content creation) is being commoditized because these tasks are primarily information processing, which is exactly what AI excels at. Manual trades involve physical presence, spatial reasoning, and real-world problem-solving that current AI cannot perform.
Priestley highlights the massive AI infrastructure investment happening now, with $650 billion being spent on AI compute this year alone. Those data center computers last only three to four years before replacement. This creates both enormous opportunity and significant financial risk if the returns don't materialize.
When AI makes information processing abundant and cheap, the scarce resource becomes physical capability and human judgment in the real world. This follows historical patterns where technologies that automate one type of work increase the relative value of complementary work that cannot be automated.
Priestley's core argument is that AI creates abundance in knowledge work, driving down its price, while physical trades remain scarce and increase in relative value. The professionals who thrive will combine AI leverage with irreplaceable human capabilities: physical presence, entrepreneurial thinking, personal brand, and authentic human connection. His prediction that plumbers will earn more than lawyers by 2029 is not hyperbole but a natural consequence of how technology reshapes labor markets.
