ATMs didn’t kill bank teller jobs, but the iPhone did

Original Article ↗ Hacker News Discussion ↗

Automation in banking is being re-examined through the lens of history: ATMs reduced the need for tellers per branch but coincided with a boom in new branches, while online and especially mobile banking have since sharply reduced in-person banking and teller roles. Many argue this shift is driven less by smartphones themselves and more by a broader move to cashless payments, direct deposit, and app-based services that make branches largely obsolete. Commenters use this as a case study for thinking about AI: technology that first augments existing structures can later enable entirely new paradigms that remove whole layers of jobs, with uncertain implications for employment, inequality, and the nature of future work.

Drivers of Teller Decline

  • Many argue the main cause is the shift to cashless payments (cards, ACH, online bill pay), not smartphones per se. Less cash use ⇒ fewer in-branch cash transactions.
  • Direct deposit and electronic transfers further reduced branch visits; tellers increasingly only needed for edge cases (large cash, special instruments, problems).
  • ATMs clearly reduced tellers per branch, but deregulation and branch expansion offset this for a time; population growth makes flat teller counts effectively a decline.

Role of Smartphones vs Internet

  • Several commenters say “the internet” and web banking, not the iPhone, did the heavy lifting.
  • Others note smartphones were crucial for:
    • Mobile check deposit via camera.
    • P2P apps (Venmo, Cash App) for small transfers that were awkward with cards.
    • Always-available access that fits modern habits (“do it now on my phone or forget”).

Banking Apps vs Web Banking

  • Some prefer desktop/web for better screen, keyboard, exports, open banking, and advanced features.
  • Others find apps faster and lower friction (Face ID, persistent login, push alerts, card controls).
  • Banks often push users to apps: some features are app-only, web UX is degraded, or browser access (esp. on Linux) breaks.

Cashless, Checks, and Regional Differences

  • Europeans and some others report checks are essentially obsolete; transfers use IBAN and mobile payment systems.
  • In the US, checks still appear for rent, contractors, rebates, or older relatives, though far less than decades ago.
  • Mobile check deposit is repeatedly cited as the last big reason not to visit a branch.

What Tellers and Branches Do Now

  • Tellers increasingly act as greeters, upsellers, and handlers of edge cases: large withdrawals, special denominations, business cash deposits, account lockouts.
  • Branches are described as loan– and product–sales centers with a small teller area.

Critiques of the Article and Data

  • Multiple people call out the “fell off a cliff” graph for a non-zero y-axis; the drop is ~60%, still large but visually exaggerated.
  • Some say tying this specifically to the iPhone is post hoc and clickbait; the 2008 crisis, consolidation, and long-planned cost cutting are under-discussed.
  • Correlation vs causation is debated; several find the ATM → more branches → then mobile → fewer branches story oversimplified.

Parallels to AI and Future of Work

  • Commenters map ATMs vs mobile banking onto “AI as tool” vs “AI enabling new firm structures.”
  • There is extensive debate on whether AI will mirror ATMs (productivity, job reshaping) or mobile banking (true job elimination), with strong arguments on both sides and no consensus.
