ATMs didn't kill bank Teller jobs, but the iPhone did
J. D. Vance's favorite economic parable about ATMs and bank tellers is apparently wrong. This article delves into how task automation (ATMs) expanded the banking sector and repurposed tellers, while mobile banking (iPhone) fundamentally shifted the paradigm, leading to significant job displacement. It offers a crucial lesson for anticipating the future impact of AI, suggesting that true disruption comes from new paradigms, not merely automating existing tasks.
The Lowdown
The article debunks a popular economic parable, often cited by figures like J. D. Vance, that ATMs did not reduce bank teller employment. While this was historically true for decades, the author reveals that bank teller jobs have, in fact, significantly declined since the 2010s, with the iPhone and the rise of mobile banking being the true culprits.
- ATM's initial impact: ATMs, introduced in the 1970s, automated routine tasks for tellers. However, instead of reducing employment, they made bank branches cheaper to operate, leading to an increase in branch numbers and tellers being repurposed for "relationship banking," expanding the overall industry.
- The "iPhone" paradigm shift: The smartphone, particularly the iPhone and its subsequent mobile banking ecosystem, fundamentally changed how people interacted with banks. It removed the need for physical branch visits for most transactions, leading to widespread branch closures and a dramatic decline in teller employment.
- Key distinction: The core argument is that task automation within an existing paradigm (ATMs making teller tasks more efficient) often leads to complementarity and job evolution, whereas the creation of entirely new paradigms (mobile banking rendering physical branches obsolete) is what causes significant job displacement.
- AI implications: This distinction holds important lessons for the impact of AI. The author suggests that AI simply acting as "drop-in remote workers" (task automation) will face friction and have limited displacement effects. Real productivity gains and job loss from AI will occur when entirely new "fully-automated firms" or paradigms emerge, organizing work completely around AI capabilities.
The article concludes by emphasizing that while the ATM parable offers comfort, it only tells half the story. Understanding the difference between task automation and paradigm replacement is crucial for accurately predicting technology's future impact on labor markets, especially with AI.
The Gossip
Mobile Misattribution
Many commenters debated whether the "iPhone" specifically was the job killer, or if it was broader mobile banking, online banking, and the overall shift to a cashless society. Some pointed out that online banking and other smartphones existed before, questioning the iPhone's unique role, while others argued the iPhone's ease of use and app ecosystem significantly accelerated adoption. The conversation included discussion on the user experience of apps vs. web browsers for banking, with points on convenience, security, and accessibility for those whose mobile device is their primary computer.
Automated Anxieties and Ambitions
The discussion often circled back to the article's core thesis regarding AI. Commenters debated whether AI would primarily automate tasks within existing roles or fundamentally redefine industries through "fully automated firms." Skepticism was voiced regarding the practicality of fully automated firms without human responsibility for outcomes (liability), and the definition of "thinking" in AI sparked philosophical questions. The broader implications for job markets, including potential for job polarization and increased income inequality, were also significant concerns.
Numerical Nuances and Narrative Naysayers
A point of contention was the article's portrayal of the decline in bank teller employment as "falling off a cliff." While the graph showed a substantial reduction (around 60%), some argued against the dramatic phrasing and the non-zero-based Y-axis, suggesting it visually exaggerated the drop. The 2008 financial crisis was also cited as a potential contributing factor to bank branch closures, challenging the direct causal link solely to mobile banking.
