Agents Take the First-Year Work and Thin the Senior Bench

This piece follows one change downstream. Agents now absorb the discrete tasks that first-year staff once learned on, and firms are responding by hiring fewer juniors.

Key points

• The best agent now succeeds half the time on tasks that take a skilled person about five hours¹.
• Employment of workers aged 22 to 25 in AI-exposed occupations sits 19 percent below trend, and reduced hiring drives the gap².
• Fixed fees and outcome pricing remove the client payment that once funded junior training³⁴.
• Firms that stop training juniors will likely compete for a shrinking pool of seniors by 2030⁵.
• New disclosure laws track AI layoffs and miss the quieter cut in entry hiring⁶.

The change

METR puts the best agent's 50 percent time horizon at 320 minutes¹. That horizon has doubled every 131 days since 2023¹. Agents still fail most end-to-end professional projects. The top Remote Labor Index score is about 16 percent⁷. We weighed that tension in our contradictions piece. Employers are acting on the trend line anyway. In 2025, 17 percent of CEOs planned to shift away from junior roles. In 2026 the share is 43 percent⁵. A Dallas Fed paper finds that AI substitutes for entry-level workers and complements experienced ones⁸.

What follows

First-order

• Tool budgets beat training budgets. At one forum of law firm COOs and CFOs, nearly every table protected the AI drafting platform and trimmed associate pay⁹.
• Elite intakes shrink first. Linklaters cut trainee places from 100 to 60. Freshfields cut from 85 to 70¹⁰.
• Clients start pricing out junior hours. Citigroup asks bidding firms to show AI savings. Morgan Stanley plans more fixed fees³.
• Software drops the seat. Zendesk charges 1.50 dollars per automated resolution⁴. Each resolution billed this way replaces work a junior support seat once did.
• Shadow side. A half-reliable agent still needs a human checker. Firms that cut juniors lose the people who learn by doing that checking¹.

Second-order

• Junior training loses its payer. Under a fixed fee, first-year hours become a cost paid from partner profit³. We judge it likely that most firms cut that cost in a down year⁹.
• Experience earns a wider premium. Wages in computer systems design rose 16.7 percent since fall 2022⁸. National wages rose 7.5 percent over the same period⁸.
• The degree is worth less. The US college wage premium fell from about 87 percent in 2022 to about 78 percent in 2026¹¹. A working paper that has not been peer reviewed assigns AI about 30 percent of the drop¹¹.
• Training splits in two. Ropes and Gray credits 20 percent of first-year billable hours to AI learning¹². Weil runs a ten-week AI program for 1L summer associates¹². Prompting skill teaches a first-year little about reading a contract.

Third-order

• A senior gap opens. Finance leaders already name senior accountants as their hardest hire⁵. Firms that buy seniors externally assume someone else trained them. If junior hiring stays below trend, we put about 60 percent odds on visible senior shortages in law, finance, and software by 2030.
• Tacit skill loses its source. Senior judgment grows from years of codified work⁸. Automating the first rung removes the path to the second.
• Cheap capability spreads the effect. Open-weight models trail the closed frontier by about four months¹³. Small firms and offshore rivals will plausibly gain junior-grade agents at low cost within a year of each frontier release.
• Policy watches the wrong door. California, Connecticut, and New York now require AI disclosure in layoff notices⁶. A firm that quietly stops hiring juniors files nothing⁶. The pending federal SKILL Act would pay employers credits for hiring graduates⁶.

Who gains, who loses

• Experienced specialists gain pricing power as the supply behind them thins⁸⁵.
• Vendors paid per outcome capture budget that once paid junior salaries⁴.
• Graduates from 2026 to 2028 lose entry points and carry debt priced on the old premium¹¹.
• Firms that fund training like pilot simulator hours plausibly build the next senior bench⁹.
• Firms that rely on hiring seniors away from rivals lose once every competitor tries the same move⁵.

A glimpse ahead

Spring 2030. A mid-size firm posts a role for a fifth-year associate. The salary band sits far above its 2026 level. Twelve applications arrive. Nine come from lawyers at rival firms who will draw counteroffers. The hiring partner checks the class of 2025 and finds it was half the usual size. She opens a second posting for six first-years. It promises 400 credited hours of simulated depositions. Finance flags the line as unbillable. She approves it anyway.
