Coding is solved, builders remain

Sunday, June 28, 2026 · from 4 podcasts
  • At Anthropic, AI agents now write 100% of code, ending manual syntax work.
  • Junior engineering roles vanish as firms automate with unlimited token budgets.
  • Designers, not engineers, lead AI prompting with visual vocabulary.

Coding is no longer a bottleneck. At Anthropic, Boris Cherny hasn’t touched raw syntax since November 2024. He ships 10 to 30 pull requests daily by managing five concurrent AI agents. According to Cherny on Lenny's Podcast, the title 'software engineer' is obsolete - replaced by 'builder' - as agents handle everything from bash scripting to memory leak fixes.

The shift is structural. A SemiAnalysis report found Claude Code now authors 4% of all public GitHub commits, a figure Cherny says is far higher in private repos. Anthropic’s internal data shows a 200% increase in pull requests per engineer since adopting agent teams. This isn’t incremental gain - it’s a collapse of the old workflow. Cherny argues the printing press is the closest analogy: a craft once reserved for scribes becomes universal.

Management doctrine has flipped. Instead of hiring more people, Anthropic underfunds projects to force automation. Engineers get unlimited token budgets, spending hundreds of thousands per month to experiment freely. Cost optimization comes later, after the system proves viable. "Claudify the workflow" is now cultural dogma.

"We're moving from UX to AX - Agentic Experience. Design is no longer about the screen. It's about designing for robots, for command lines, for 'dash-dash help.'"

- John Maeda, The a16z Show

Maeda’s insight reframes the stakes. Designers, not engineers, are now ahead in the AI era. Paul Backus observed that designers outperform engineers in AI prompting because they use precise visual language - 'negative space,' 'rhythm,' 'quieter' - that steers models more effectively. His tool Impeccable encodes this lexicon into agent behavior, fighting 'AI slop' with anti-attractors and randomness.

This isn’t just about aesthetics. As AI agents replace junior coders at Google and Meta, the real divide is cognitive. Engineers think in execution; designers think in constraints. John Maeda recalls Bill Atkinson’s region-based Floodfill API - something Windows lacked - as proof that architectural vision beats brute force. In an AX world, that vision becomes the differentiator.

The talent war confirms the shift. OpenAI is poaching Apple hardware leads like Paul Meade, signaling a move beyond software. Sam Altman isn’t building tools - he’s building ecosystems. Meanwhile, Planet’s Will Marshall is launching orbital data centers to escape terrestrial power limits, proving that the next frontier isn’t code, but infrastructure shaped by AI reasoning.

China’s GLM 5.2 model now matches US frontier AI through algorithmic efficiency, not just scale. The race is no longer about H100s - it’s about intelligence per watt. When agents write their own diagnostics and optimize their own loops, the human role shifts from coder to compass.

  • Planet has indexed the Earth for searchability over the last decade, accumulating a 150-petabyte archive of 3,000 images for every landmass point. This historical data is crucial for comparing current conditions to past norms.
  • Planet is placing Nvidia chips on its satellites for edge processing and satellite-to-satellite communication, significantly reducing data analysis time from hours to seconds for time-critical applications like disaster response.
  • Project Suncatcher involves putting TPUs for Google into orbit, an early step towards orbital AI compute. A Google study suggests compute in orbit will be cheaper than terrestrial when launch costs reach $200-$300 per kilogram.

Space (2)

  • Planet's satellite fleets offer varied resolutions: a scanning fleet (Owl) upgrading from 3-meter to 1-meter, a high-resolution system aiming for 30-centimeter daily imagery, and a Tanager hyperspectral imager with 400 spectral bands.
  • Will Marshall argues that while launch costs are important, the long-term competitive advantage in orbital compute will depend more on compute efficiency (flops per watt) than on raw launch capacity.

Climate (1)

  • Will Marshall maintains Earth is by far the best planet, emphasizing the need to protect its unique biosphere. Space technology's primary role should be to help manage Earth intelligently, not solely for off-world colonization.

Models (1)

  • Alex argues that Google DeepMind has fallen behind OpenAI and Anthropic in frontier AI models, influencing top researchers to seek raw access to cutting-edge models in smaller, more agile organizations.

Robotics (1)

  • Will Marshall believes that AI needs to interact with the physical world through sensors and actuators to achieve true intelligence and consciousness, moving beyond current 'brains in a vat' large language models.

What Happens to Design After AI?Jun 24

  • Paul Backus developed Impeccable after observing designers achieved superior Claude results from their specialized vocabulary. His open-source agent skill embeds this language, adds a quality layer to remove "slop," and features a visual iteration mode.
  • John Maeda, recalling MIT discussions from the 1990s, expresses excitement about "auto design" finally being highly feasible, fulfilling a decades-long vision.
  • Paul Backus highlights Muriel Cooper's 1980s work at MIT, where she predicted electronic publishing and collaborated with the AI lab on automating design through machine intelligence.
  • John Maeda distinguishes design from engineering, noting design requires restraint - like an architect shaping human experience - whereas engineering often builds everything it can.
  • John Maeda likens Impeccable to Kai's Power Tools, which broadened Photoshop's market through algorithmic effects. He also calls it a "PostScript moment," praising its encoding of visual graphic design primitives.
  • John Maeda is integrating Impeccable into the new GitHub Co-pilot app, aiming to elevate design craft within the "digital harness age" by setting a high bar for application quality.
  • Paul Backus notes "AI slop" evolves from "purple gradients" to current tells like "beige backgrounds." Impeccable combats this algorithmic homogeneity using "anti-attractors" and randomness to ensure unique design outcomes.
  • John Maeda advocates shifting from UX to AX (Agentic Experience) design, concentrating on non-visual interactions for agents (e.g., CLI, error messages) to force-multiply design capabilities beyond traditional interfaces.
  • John Maeda credits Bill Atkinson's Macintosh QuickDraw API, with its unique region-based routines like Floodfill, as foundational for Photoshop's development, a capability absent in Windows' DirectX at the time.
  • John Maeda defines conviction in leaders as a rare blend of design, business, and technical sense, enabling bets aimed at "global maximums" rather than local optimization.
  • Paul Backus finds Impeccable shapes both design and engineering mindsets, leading to improved communication as users adopt each other's technical and design vocabularies through interaction with the tool.
  • Anisha A. references John Maeda's 2010 Forbes prediction that by 2020, the software industry would rediscover its craft heritage, shifting towards bespoke apps and valuing authorship.

Models (4)

  • Paul Backus explains LLMs, trained on humanity's output rather than the input (design rationale), possess millions of taste definitions but only approximate taste, failing to grasp its underlying human viewpoint or origins.
  • Anisha A. highlights a debate on AI's impact, with some predicting design commoditization as AI enables anyone to generate interfaces via prompts.
  • Paul Backus argues AI "raises the floor" by automating mechanical design tasks, allowing humans to focus on higher-level thinking and "raise the ceiling" of creative output.
  • John Maeda explains current vision models lack adequate training data to "see" and think like human designers, especially regarding motion and temporal resolution in design outputs.

History (1)

  • John Maeda posits design became critical around 2014-2015 due to mobile's rise. Frequent mobile usage made poor experiences painful, unlike less-used desktop interfaces, demanding higher design quality.

Society (1)

  • John Maeda asserts taste is cultural and develops from material scarcity. He contrasts evolved design cultures like Denmark and Japan with the U.S. "styrofoam plate," noting royalty's desire for distinctiveness historically drove taste.

Culture (1)

  • Paul Backus recounts how Steve Jobs tested employee conviction by challenging their ideas, often saying "that's a stupid idea," to see if they would defend their vision or simply acquiesce.

Reasoning (1)

  • Paul Backus differentiates "cognitive surrender" (passively accepting AI decisions) from "cognitive delegation" (using AI to aid, but retaining human control), advocating for active, collaborative human-AI interaction.

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.
  • 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.
  • 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.

AI Infrastructure (3)

  • 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.
  • Cherny advises builders to design for the AI model six months from now, not its current capabilities. He warns against over-engineering workflows, arguing the more general model will always outperform a specialized, scaffolded one.
  • 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.
