    The third golden age of software engineering – thanks to AI, with Grady Booch

    Brought to You By: • Statsig — ⁠ The unified platform for flags, analytics, experiments, and more. • Sonar – The makers of SonarQube, the industry standard for automated code review • WorkOS – Everything you need to make your app enterprise ready. — Every few decades, software engineering is declared “dead” or on the verge of being automated away. We’ve heard versions of this story before. But what if it’s just the start of a new “golden age” of a different type of software engineering, like it has been many times before? In this episode of The Pragmatic Engineer, I’m joined once again by Grady Booch, one of the most influential figures in the history of software engineering, to put today’s claims about AI and automation into historical context. Grady is the co-creator of the Unified Modeling Language, author of several books and papers that have shaped modern software development, and Chief Scientist for Software Engineering at IBM, where he focuses on embodied cognition. Grady shares his perspective on three golden ages of computing since the 1940s, and how each emerged in response to the constraints of its time. He explains how technical limits and human factors have always shaped the systems we build, and why periods of rapid change tend to produce both real progress and inflated expectations. He also responds to current claims that software engineering will soon be fully automated, explaining why systems thinking, human judgment, and responsibility remain central to the work, even as tools continue to evolve. — Timestamps (00:00) Intro (01:04) The first golden age of software engineering (18:05) The software crisis (32:07) The second golden age of software engineering  (41:27) Y2K and the Dotcom crash  (44:53) Early AI  (46:40) The third golden age of software engineering  (50:54) Why software engineers will very much be needed (57:52) Grady responds to Dario Amodei (1:06:00) New skills engineers will need to succeed (1:09:10) Resources for studying complex systems  (1:13:39) How to thrive during periods of change — The Pragmatic Engineer deepdives relevant for this episode: • When AI writes almost all code, what happens to software engineering?  • Inside a five-year-old startup’s rapid AI makeover • Software architecture with Grady Booch • What is old is new again — Production and marketing by ⁠⁠⁠⁠⁠⁠⁠⁠https://penname.co/⁠⁠⁠⁠⁠⁠⁠⁠.

    The creator of Clawd: "I ship code I don't read"

    Brought to You By: • Statsig — ⁠ The unified platform for flags, analytics, experiments, and more. • Sonar – The makers of SonarQube, the industry standard for automated code review • WorkOS – Everything you need to make your app enterprise ready. — Peter Steinberger ships more code than I’ve seen a single person do: in January, he was at more than 6,600 commits alone. As he puts it: “From the commits, it might appear like it's a company. But it’s not. This is one dude sitting at home having fun." How does he do it? Peter Steinberger is the creator of Clawdbot (as of yesterday: renamed to Moltbot) and founder of PSPDFKit. Moltbot – a work-in-progress AI agent that shows what the future of Siri could be like – is currently the hottest AI project in the tech industry, with more searches on Google than Claude Code or Codex. I sat down with Peter in London to talk about what building software looks like when you go all-in with AI tools like Claude and Codex. Peter’s background is fascinating. He built and scaled PSPDFKit into a global developer tools business. Then, after a three-year break, he returned to building. This time, LLMs and AI agents sit at the center of his workflow. We discuss what changes when one person can operate like a team and why closing the loop between code, tests, and feedback becomes a prerequisite for working effectively with AI. We also go into how engineering judgment shifts with AI, how testing and planning evolve when agents are involved, and which skills and habits are needed to work effectively. This is a grounded conversation about real workflows and real tradeoffs, and about designing systems that can test and improve themselves. — Timestamps (00:00) Intro (01:07) How Peter got into tech  (08:27) PSPDFKit (19:14) PSPDFKit’s tech stack and culture (22:33) Enterprise pricing (29:42) Burnout  (34:54) Peter finding his spark again (43:02) Peter’s workflow  (49:10) Managing agents  (54:08) Agentic engineering (59:01) Testing and debugging  (1:03:49) Why devs struggle with LLM coding (1:07:20) How PSPDFkit would look if built today  (1:11:10) How planning has changed with AI  (1:21:14) Building Clawdbot (now: Moltbot) (1:34:22) AI’s impact on large companies (1:38:38) “I don’t care about CI” (1:40:01) Peter’s process for new features  (1:44:48) Advice for new grads (1:50:18) Rapid fire round — The Pragmatic Engineer deepdives relevant for this episode: • Inside a five-year-old startup’s rapid AI makeover • When AI writes almost all code, what happens to software engineering? • Why it’s so dramatic that “writing code by hand is dead” • AI Engineering in the real world • The AI Engineering stack — Production and marketing by ⁠⁠⁠⁠⁠⁠⁠⁠https://penname.co/⁠⁠⁠⁠⁠⁠⁠⁠.

    Brought to You By: • Statsig — ⁠ The unified platform for flags, analytics, experiments, and more. • Sonar – The makers of SonarQube, the industry standard for automated code review • WorkOS – Everything you need to make your app enterprise ready. — Amazon S3 is one of the largest distributed systems ever built, storing and serving data for a significant portion of the internet. Behind its simple interfaces hides an enormous amount of engineering work, careful tradeoffs, and long-term thinking. In this episode, I sit down with Mai-Lan Tomsen Bukovec, VP of Data and Analytics at AWS, who has been running Amazon S3 for more than a decade. Mai-Lan shares how S3 operates at extreme scale, what it takes to design for durability and availability across millions of servers, and why building for failure is a core principle. We also go deep into how AWS approaches correctness using formal methods, how storage tiers and limits shape system design, and why simplicity remains one of the hardest and most important goals at S3’s scale. — Timestamps (00:00) Intro (01:03) S3’s scale  (03:58) How S3 started  (07:25) Parquet, Iceberg, and S3 tables (09:46) S3 for developers  (13:37) Why AWS keeps S3 prices low  (17:10) AWS pricing tiers (19:38) Availability and durability  (26:21) The cost of S3's consistency (31:22) Automated reasoning and proof of correctness  (35:14) Durability at AWS scale (39:58) Correlated failure and crash consistency  (43:22) Failure allowances  (46:04) Two opposing principles in S3 design (49:09) S3’s evolution  (52:21) S3 Vectors  (1:01:16) The 50 TB limit on AWS (1:07:54) The simplicity principle (1:10:10) Types of engineers working on S3 (1:14:15) Closing recommendations  — The Pragmatic Engineer deepdives relevant for this episode: • Inside Amazon’s engineering culture • How AWS deals with a major outage • A Day in the Life of a Senior Manager at Amazon • What is a Principal Engineer at Amazon? – with Steve Huynh • Working at Amazon as a software engineer – with Dave Anderson Amazon papers recommended by Mai-Lan: • Using lightweight formal methods to validate a key-value storage node in Amazon S3 • Formally verified cloud-scale authorization • Analyzing metastable failures • Amazon’s engineering tenets — Production and marketing by ⁠⁠⁠⁠⁠⁠⁠⁠https://penname.co/⁠⁠⁠⁠⁠⁠⁠⁠.

Engineering teams today move much faster, thanks to AI. Because of this, coordination increasingly becomes a problem. This is where Linear helps fast-moving teams stay focused. Check out Linear. — As software engineers, what should we know about writing secure code? Johannes Dahse is the VP of Code Security at Sonar and a security expert with 20 years of industry experience. In today’s episode of The Pragmatic Engineer, he joins me to talk about what security teams actually do, what developers should own, and where real-world risk enters modern codebases. We cover dependency risk, software composition analysis, CVEs, dynamic testing, and how everyday development practices affect security outcomes. Johannes also explains where AI meaningfully helps, where it introduces new failure modes, and why understanding the code you write and ship remains the most reliable defense.

    How AI will change software engineering – with Martin Fowler

    Brought to You By: •⁠ Statsig ⁠ — ⁠ The unified platform for flags, analytics, experiments, and more. AI-accelerated development isn’t just about shipping faster: it’s about measuring whether, what you ship, actually delivers value. This is where modern experimentation with Statsig comes in. Check it out. •⁠ Linear ⁠ — ⁠ The system for modern product development. I had a jaw-dropping experience when I dropped in for the weekly “Quality Wednesdays” meeting at Linear. Every week, every dev fixes at least one quality isse, large or small. Even if it’s one pixel misalignment, like this one. I’ve yet to see a team obsess this much about quality. Read more about how Linear does Quality Wednesdays – it’s fascinating! — Martin Fowler is one of the most influential people within software architecture, and the broader tech industry. He is the Chief Scientist at Thoughtworks and the author of Refactoring and Patterns of Enterprise Application Architecture, and several other books. He has spent decades shaping how engineers think about design, architecture, and process, and regularly publishes on his blog, MartinFowler.com. In this episode, we discuss how AI is changing software development: the shift from deterministic to non-deterministic coding; where generative models help with legacy code; and the narrow but useful cases for vibe coding. Martin explains why LLM output must be tested rigorously, why refactoring is more important than ever, and how combining AI tools with deterministic techniques may be what engineering teams need. We also revisit the origins of the Agile Manifesto and talk about why, despite rapid changes in tooling and workflows, the skills that make a great engineer remain largely unchanged. — Timestamps (00:00) Intro (01:50) How Martin got into software engineering  (07:48) Joining Thoughtworks  (10:07) The Thoughtworks Technology Radar (16:45) From Assembly to high-level languages (25:08) Non-determinism  (33:38) Vibe coding (39:22) StackOverflow vs. coding with AI (43:25) Importance of testing with LLMs  (50:45) LLMs for enterprise software (56:38) Why Martin wrote Refactoring  (1:02:15) Why refactoring is so relevant today (1:06:10) Using LLMs with deterministic tools (1:07:36) Patterns of Enterprise Application Architecture (1:18:26) The Agile Manifesto  (1:28:35) How Martin learns about AI  (1:34:58) Advice for junior engineers  (1:37:44) The state of the tech industry today (1:42:40) Rapid fire round — The Pragmatic Engineer deepdives relevant for this episode: • Vibe coding as a software engineer • The AI Engineering stack • AI Engineering in the real world • What changed in 50 years of computing — Production and marketing by ⁠⁠⁠⁠⁠⁠⁠⁠https://penname.co/⁠⁠⁠⁠⁠⁠⁠⁠.

    Netflix’s Engineering Culture

    Brought to You By: •⁠ Statsig ⁠ — ⁠ The unified platform for flags, analytics, experiments, and more. Statsig enables two cultures at once: continuous shipping and experimentation. Companies like Notion went from single-digit experiments per quarter to over 300 experiments with Statsig. Start using Statsig with a generous free tier, and a $50K startup program. •⁠ Linear ⁠ — ⁠ The system for modern product development. When most companies hit real scale, they start to slow down, and are faced with “process debt.” This often hits software engineers the most. Companies switch to Linear to hit a hard reset on this process debt – ones like Scale cut their bug resolution in half after the switch. Check out Linear’s migration guide for details. — What’s it like to work as a software engineer inside one of the world’s biggest streaming companies? In this special episode recorded at Netflix’s headquarters in Los Gatos, I sit down with Elizabeth Stone, Netflix’s Chief Technology Officer. Before becoming CTO, Elizabeth led data and insights at Netflix and was VP of Science at Lyft. She brings a rare mix of technical depth, product thinking, and people leadership. We discuss what it means to be “unusually responsible” at Netflix, how engineers make decisions without layers of approval, and how the company balances autonomy with guardrails for high-stakes projects like Netflix Live. Elizabeth shares how teams self-reflect and learn from outages and failures, why Netflix doesn’t do formal performance reviews, and what new grads bring to a company known for hiring experienced engineers. This episode offers a rare inside look at how Netflix engineers build, learn, and lead at a global scale. — Timestamps (00:00) Intro (01:44) The scale of Netflix  (03:31) Production software stack (05:20) Engineering challenges in production (06:38) How the Open Connect delivery network works (08:30) From pitch to play  (11:31) How Netflix enables engineers to make decisions  (13:26) Building Netflix Live for global sports (16:25) Learnings from Paul vs. Tyson for NFL Live (17:47) Inside the control room  (20:35) What being unusually responsible looks like (24:15) Balancing team autonomy with guardrails for Live (30:55) The high talent bar and introduction of levels at Netflix (36:01) The Keeper Test   (41:27) Why engineers leave or stay  (44:27) How AI tools are used at Netflix (47:54) AI’s highest-impact use cases (50:20) What new grads add and why senior talent still matters (53:25) Open source at Netflix  (57:07) Elizabeth’s parting advice for new engineers to succeed at Netflix  — The Pragmatic Engineer deepdives relevant for this episode: • The end of the senior-only level at Netflix • Netflix revamps its compensation philosophy • Live streaming at world-record scale with Ashutosh Agrawal • Shipping to production • What is good software architecture? — Production and marketing by ⁠⁠⁠⁠⁠⁠⁠⁠https://penname.co/⁠⁠⁠⁠⁠⁠⁠⁠.
