AI agents replace junior coders at startups

Friday, June 26, 2026 · from 5 podcasts
  • Startups now run with one engineer managing five AI agents, replacing entire junior teams.
  • Coding is no longer a bottleneck - it’s a coordination problem.
  • CEOs who treat AI as strategy see 3x ROI; others are flying blind.

A single engineer at Anthropic now ships 30 pull requests a day. Boris Cherny doesn’t write code by hand anymore - his agents do. Since November 2024, he hasn’t manually edited a line. Instead, he runs five concurrent AI agents through Claude Code, automating tasks once reserved for junior developers.

This isn’t prototyping. At Anthropic, pull requests per engineer have tripled. A SemiAnalysis report found Claude Code now authors 4% of all public GitHub commits - and internal data suggests it’s higher in private repos. The model doesn’t just autocomplete; it debugs memory leaks, writes bash scripts, and runs diagnostics. The software engineer, as a role, is being redefined.

Cherny calls it 'management by underfunding.' Give one person a three-person task, and they’ll automate to survive. He advises startups to stop optimizing for inference costs early. Instead, give engineers unlimited tokens. Only after automation works should they optimize - switching from Opus to Haiku, for example. Cost discipline comes downstream, not upstream.

"Coding is virtually solved for what I do. The title 'software engineer' will fade. Everyone will be a builder."

- Boris Cherny, Lenny's Podcast

That shift is already visible outside Silicon Valley. At podcasting infrastructure project Podcast Index, Dave Jones went from writing 100% of the code to just 10% in two months. He’s not celebrating. For Jones, the struggle was the signal - if building wasn’t hard, maybe it wasn’t worth doing. Adam Curry disagrees, recalling how digital production felt like a video game at first, then unlocked new creative modes.

The real divide isn’t generational - it’s mental. Junior engineers at Anthropic use Claude Code more aggressively than veterans. One debugged a memory leak faster with AI than Cherny could by hand. The old guard sees tools; the new cohort sees co-workers. That’s why Anthropic expects every function - finance, design, legal - to ship pull requests. The builder is becoming universal.

But not all AI spending delivers. According to a KPMG Pulse Survey, 76% of leaders claim AI drives value - yet only 21% of IT-led initiatives deliver ROI. The gap collapses when CEOs own the strategy. Organizations with CEO accountability are three times more likely to report meaningful returns. It’s no longer about efficiency - it’s about redesigning who does what.

"When CEOs treat AI as strategy, 57% report value. When it’s an IT project, it’s 21%."

- Nathaniel Whittemore, The AI Daily Brief

The labs know this. OpenAI built its own chip, Jalapeño, in nine months using AI to design the silicon. Broadcom confirms orders stretch to 2028. Meanwhile, Anthropic accuses Alibaba of a 29-million-query distillation attack - harvesting outputs to clone U.S. models. The AI race is no longer just technical. It’s structural, geopolitical, and organizational.

  • Donald Trump stated on Truth Social he would refuse to sign bipartisan housing affordability legislation until Congress passes his 'Save America Act,' which he calls a 'national emergency.'
  • Ryan Grim noted the bipartisan housing bill stems from an executive order Elizabeth Warren supported, aiming to block permanent capital from buying houses.
  • Krystal Ball explained the proposed 'Save America Act' would make voting harder by requiring states to provide voter rolls, leading to automatic removal of voters, particularly targeting those suspected of being Democratic voters.
  • The Postmaster General's directive threatened to withhold mail ballot delivery from states that do not share their voter rolls with the Trump administration, weaponizing postal services for voter control.
  • The Iran War Powers resolution passed the House and Senate, reportedly causing a 'shouting match' between Donald Trump and four Senate Republicans who voted in favor, including Bill Cassidy and Rand Paul.
  • Ryan Grim highlighted Donald Trump's consistent concern with war powers votes, noting Trump previously adjusted policy, like stopping Saudi jet refueling during the Yemen War, in response to such resolutions.
  • The Iran War Powers resolution passed 50-48, providing a legal basis to challenge future direct hostilities with Iran without presidential signature; Senator Cassidy later flipped his vote after a briefing, causing a subsequent re-vote to fail.
  • Nine anti-ICE protesters were found guilty of charges including terrorism in Texas; leader Benjamin Song received a 100-year sentence, with six others getting 50-70 years.
  • Daniel Sanchez Estrata, a defendant not present at the ICE protest, was sentenced to 30 years for moving leftist literature at his arrested wife's request, charged with 'corruptly concealing a document or record.'

  • Benedict Evans argues that foundation models are not products but rather commodities, with the real value expected to emerge higher up the application stack.
  • Agentic coding has achieved significant product-market fit, leading to a massive focus within the tech industry and creating a supply crunch for AI capacity.
  • Determining the impact of agentic coding on engineering jobs and team structures is premature, as the market is in flux due to ongoing supply-demand imbalances and pricing issues.
  • Corporations are using LLMs for specific back-office automation, such as cash flow forecasting for commodities companies, a distinct application from general chatbot interactions.
  • The rapid growth in AI infrastructure spending, with mobile data traffic rising by 1,500 to 2,000 times since 2009-2010, parallels historical patterns of accelerating tech adoption.
  • Despite mobile networks generating around $1 trillion in revenue and spending $200 billion annually on capex, they captured little value; most accrued to applications built on top.
  • Foundation models lack the network effects of platforms like Windows or iOS, making their long-term ability to differentiate or exert pricing power uncertain.
  • Benedict Evans projects three to six companies will develop frontier models, investing $200 billion to $2 trillion annually, which suggests future commoditization.
  • The high capex of major tech companies (Google, Meta, Microsoft spending over 50% of revenue) is unsustainable long-term and indicates a future slowdown due to financial gravity.
  • Large tech firms face an existential FOMO, compelling heavy AI investment to avoid falling behind, even as CFOs question the long-term returns and sustainability of such spending.
  • Measuring AI's return on investment is currently challenging because many benefits, like improved analytics or customer support, are difficult to quantify financially.
  • AI enables automation, making previously impossible tasks affordable and unlocking new business models, similar to Spotify's impact on music distribution.

  • The ultimate challenge for AI is expanding beyond software development productivity into the broader economy, finding diverse applications for general users and other industries.
  • In 20 years, AI will likely be perceived as commonplace "magic," similar to how current computing and mobile technologies are seamlessly integrated and taken for granted.

What happens after coding is solved? | Fiona Fung (Manager of the Claude Code and Cowork Teams)Jun 21

  • Boris Cherny states that 100% of his code is written by Claude Code, with no manual edits since November 2024. He ships 10-30 pull requests daily and often runs five agents simultaneously.
  • Cherny argues coding is virtually solved for his work, and he predicts the title 'software engineer' will fade, replaced by 'builder'. He believes everyone will soon be a product manager who codes.
  • A SemiAnalysis report found Claude Code authors 4% of all GitHub commits, a figure Cherny notes is higher for private repos. The report predicts Claude Code will author one-fifth of all commits by the end of 2025.
  • Cherny says productivity per engineer at Anthropic has increased 200% since introducing Claude Code, measured by pull request volume. He contrasts this with his time at Meta, where annual productivity gains were only a few percentage points.
  • Claude Code's growth is accelerating, with daily active users doubling in the past month. Cherny built the initial prototype, called Quad CLI, as a terminal tool because the model improved too quickly for other form factors.
  • Cherny advocates underfunding projects initially to force teams to 'Claudify' and automate work with AI. He advises leaders to give engineers unlimited tokens for experimentation, then optimize costs only after an idea proves successful.
  • He sees the printing press as the best historical analog for AI's impact, enabling a transition from a specialized skill to a universal capability. He imagines a future where anyone can build software.
  • For using Claude Code, Cherny recommends always using the most capable model, starting tasks in 'plan mode', and experimenting with different interfaces beyond the terminal.
  • The Claude Co-work agent was built in 10 days using Claude Code. It emerged from observing latent demand, as users were hacking the coding tool for non-technical tasks like analyzing genomes or recovering photos.
  • Cherny describes a three-layer safety approach at Anthropic: mechanistic interpretability to study model neurons, laboratory evals, and studying model behavior in the wild through early product releases.
  • He observes that newer engineers often use Claude Code in more advanced, 'AGI-forward' ways than veterans, who can get stuck in old mental models. He cites an example where a junior engineer used Claude to debug a memory leak faster than he could manually.
