early days of Amazon,\\n[1:00:02] as we as executives\\nwere required each year\\n[1:00:07] to spend two days with customer service,\\n[1:00:10] and take calls from customers\\n[1:00:12] so that we would truly understand\\n[1:00:14] what the customers were going through.\\n[1:00:17] And not just (indistinct) executives,\\n[1:00:20] Jeff himself (indistinct).\\n[1:00:22] So, Jeff sits next to this\\ncustomer service agent.\\n[1:00:26] Phone goes and automatic system\\nalready spits up the order,\\n[1:00:30] histories of this customer.\\n[1:00:33] And before that the\\ncustomer says anything,\\n[1:00:36] the customer agent says to Jeff,\\n[1:00:38] \\\"She's gonna return that table,\\\"\\n[1:00:41] and indeed the customer\\nwants to return the table\\n[1:00:44] because it's damaged.\\n[1:00:46] Call us over, and Jeff looks\\nat the agent says, says,\\n[1:00:48] \\\"How did you know that?\\\"\\n[1:00:50] She says, \\\"Well, 70% of\\nthose tables are coming back\\n[1:00:54] because there's some drop shipper\\n[1:00:55] that actually doesn't really know\\n[1:00:57] how to package them right.\\\"\\n[1:00:59] Of course, Jeff gets everybody in the room\\n[1:01:05] and starts to think about sort of,\\n[1:01:08] (indistinct) has good intentions.\\n[1:01:10] No, of course we don't\\nwant this to happen.\\n[1:01:13] But without a mechanism, nothing changed\\n[1:01:15] because everybody already\\nhas good intentions.\\n[1:01:21] So, he introduced a new mechanism,\\n[1:01:24] Amazon's version of\\nToyota's famous Andon Cord.\\n[1:01:28] So, the Andon Cord in Toyota was,\\n[1:01:30] the principle was no car should\\nleave the production line\\n[1:01:34] with a known defect.\\n[1:01:36] And then, any engineer working on the line\\n[1:01:39] could pull this cords\\n[1:01:41] and bring the whole manufacturing\\nline to a standstill\\n[1:01:45] until the defect was fixed.\\n[1:01:48] The Andon Cord that the\\ncustomer service agents got\\n[1:01:54] was a button to make the product unviable.\\n[1:01:58] Yeah?\\n[1:01:59] That made alarms go off if the people\\n[1:02:01] that were responsible for the\\nproducts to go and fix it.\\n[1:02:04] But before this, everybody\\nalready had good intentions,\\n[1:02:09] but until we introduced the\\nmechanism, nothing changed.\\n[1:02:17] Now, let's go back to\\nour technology world.\\n[1:02:21] Mechanisms take many forms.\\n[1:02:23] Each team builds their own\\none that fits the scale,\\n[1:02:26] that new nature of their work.\\n[1:02:28] The S3 team, for example,\\n[1:02:30] uses something which they\\ncall durability reviews.\\n[1:02:35] When an engineer proposes a change\\n[1:02:37] that might touch durability, they pause,\\n[1:02:40] and model the risks.\\n[1:02:42] They write down the changes,\\n[1:02:45] they list every threat imaginable,\\n[1:02:47] map out the guardrails\\nto keep the data safe,\\n[1:02:51] and is a mechanism with\\na very powerful effect.\\n[1:02:56] It turns durability\\nfrom a property of code\\n[1:03:00] into the habit of the organization.\\n[1:03:03] It makes engineers think in\\nfailure modes, not happy paths.\\n[1:03:08] And it shows why mechanisms matter.\\n[1:03:12] They convert good intentions\\ninto consistent outcomes.\\n[1:03:21] Now, if you think about it,\\n[1:03:24] code reviews are also a mechanism.\\n[1:03:28] And I know it, we all hate code reviews.\\n[1:03:31] It's like being 12-year-old\\n[1:03:33] and standing in front of the class, yeah?\\n[1:03:37] But they were very important mechanism\\n[1:03:39] because they create a moment\\n[1:03:41] where intent and implementation meet.\\n[1:03:46] Where another engineer\\ncan question assumptions,\\n[1:03:50] and catch things that\\nyou alter no longer sees.\\n[1:03:54] In an AI driven world,\\nthey matter more than ever.\\n[1:03:59] In an AI driven world, they are crucial.\\n[1:04:03] Models can generate code faster\\nthan we can understand it.\\n[1:04:06] So, the review becomes the\\ncontrol point to restore balance.\\n[1:04:14] It is where we bring human\\njudgment back into the loop,\\n[1:04:19] and make sure that the\\nsoftware actually does\\n[1:04:23] what we expect it to do.\\n[1:04:27] I encourage all of you to continue\\n[1:04:31] and you increase your human\\nto human code reviews.\\n[1:04:37] When senior and junior engineers\\nwork through code together,\\n[1:04:42] it becomes one of the most\\n[1:04:44] effective learning mechanisms we have.\\n[1:04:47] Seniors bring pattern recognition,\\n[1:04:49] and high hard-earned judgment.\\n[1:04:52] Juniors bring fresh eyes\\nand often spot details.\\n[1:04:55] Others of, look, this is\\nhow we transfer knowledge,\\n[1:05:00] and how we grow the next\\ngeneration of builders.\\n[1:05:05] AI will change many things,\\n[1:05:09] but the craft is still\\nlearned person to person.\\n[1:05:16] So, the fourth quality in my eyes\\n[1:05:19] of the Renaissance Developer is an owner.\\n[1:05:23] You build it, you own it.\\n[1:05:29] The last quality that I\\nwanna talk to you about\\n[1:05:32] is that, I think, you, the\\nfuture Renaissance Developers,\\n[1:05:39] need to become a polymath.\\n[1:05:44] Now, it has nothing to\\ndo with math, by the way.\\n[1:05:48] It's not mathematics or maths,\\n[1:05:50] or whatever you want to call it.\\n[1:05:54] The word polymath has\\nnothing to do with that.\\n[1:05:57] It actually means many\\n[1:06:01] because the math comes from\\nthe Greek work manthanein,\\n[1:06:07] which means to learn.\\n[1:06:09] It's about having deep domain experience,\\n[1:06:12] but also have knowledge that\\nspans many different subjects.\\n[1:06:17] Da Vinci probably was\\nthe absolute best example\\n[1:06:22] of a polymath because he worked\\n[1:06:24] across so many different disciplines.\\n[1:06:27] He was a painter, he was an\\nengineer, he was an economist\\n[1:06:30] and he was an inventor.\\n[1:06:34] Now, I do not expect you\\nall to become a Da Vinci.\\n[1:06:40] Yeah?\\n[1:06:41] But you should expand your knowledge\\n[1:06:45] just beyond deep domain expertise.\\n[1:06:50] Yeah?\\n[1:06:51] This is what I would call an I-developer.\\n[1:06:57] An I-shape developer is\\nsomeone who is really deep\\n[1:07:02] and really highly specialized in one area.\\n[1:07:08] Let me tell you again an interesting story\\n[1:07:11] out of my own experience.\\n[1:07:14] This is my old mentor\\nand friend, Jim Gray.\\n[1:07:19] And Jim got a Turing Award\\n[1:07:23] because actually you\\nshould all know Jim Gray,\\n[1:07:25] because he's the inventor of transactions.\\n[1:07:28] Every transaction you do today,\\n[1:07:31] we have Jim to thank for this.\\n[1:07:34] But he also had this great\\nmind, he was interested\\n[1:07:37] in so many more things\\nthan just databases.\\n[1:07:41] And this is one of his\\nfamous sort of challenges.\\n[1:07:43] Give me 20 questions,\\n20 important questions\\n[1:07:47] that you want to ask of your data\\n[1:07:49] and I will design the system for you.\\n[1:07:53] One of the first ones he worked on was\\n[1:07:58] the Sloan Digital Sky Survey.\\n[1:08:01] This was one of the\\nfirst massive data sets\\n[1:08:05] that were out there.\\n[1:08:06] It was groundbreaking work\\nin developing the SkyServer.\\n[1:08:10] Yeah?\\n[1:08:10] Jim's in-depth knowledge\\nas a database expert\\n[1:08:14] was transformative for the\\ncomputation in astronomy data.\\n[1:08:19] There is actually a really\\nfunny story about that.\\n[1:08:24] At some moment, Jim goes\\nto Philadelphia, Baltimore,\\n[1:08:28] where the group is, and he\\nwalks into the server room.\\n[1:08:34] 30 seconds later, he walks\\nout and he tells them\\n[1:08:38] that a database layout is wrong,\\n[1:08:40] (machine rattling)\\n[1:08:42] and everybody looks at him and\\nsays, \\\"How do you know that?\\\"\\n[1:08:47] By just listening to the\\nrattling of the discs,\\n[1:08:51] he knew that there was way\\ntoo much random access.\\n[1:08:55] This intuition built from\\ndecades of experience,\\n[1:08:59] had given him a sixth sense\\nof how systems should behave.\\n[1:09:03] He tries him to redesign the architecture\\n[1:09:05] and performance improved dramatically.\\n[1:09:11] Now, Jim wasn't what I would call\\n[1:09:15] an I-shaped developer at all.\\n[1:09:18] His curiosity reached\\nfar beyond databases.\\n[1:09:23] He understood people,\\nhe understood business,\\n[1:09:26] and he understood a wide\\nrange of technologists.\\n[1:09:30] And my great technologist, I\\nwill describe him as T-shaped.\\n[1:09:36] Yeah?\\n[1:09:37] Deep in one domain, but\\nbrought an understanding.\\n[1:09:44] The skills you need to\\nbe successful in your job\\n[1:09:47] are a unique mix of personal skills,\\n[1:09:50] functional depth, industry knowledge.\\n[1:09:54] A database developer who\\nunderstands font and performance\\n[1:09:58] or cost aware architectures\\n[1:10:00] can make a better architectural choices\\n[1:10:03] because they see how their\\nwork shapes the overall system.\\n[1:10:10] That breadth of knowledge\\ngives you the perspective\\n[1:10:14] to improve what you build\\n[1:10:16] because you understand the trade-offs.\\n[1:10:22] T-shaped developers\\ncombine depth with breadth.\\n[1:10:28] They can dive deep into\\na specific problems,\\n[1:10:30] but we'll also understand how\\nit fits into a larger system.\\n[1:10:36] That is my advice to\\nall of you, build both.\\n[1:10:42] Develop depth in your\\ndomain, but cultivate,\\n[1:10:47] cultivate the range to connect\\n[1:10:50] to multiple disciplines and ideas.\\n[1:10:55] So, the last takeaway from\\nthe Renaissance Developer\\n[1:10:57] is become a polymath.\\n[1:11:00] Well, I don't expect\\nyou all to become that,\\n[1:11:03] but you should broaden your T.\\n[1:11:05] Great developers are T-shaped.\\n[1:11:09] They're experts in their field\\n[1:11:10] who understand their work\\nfits into a larger system.\\n[1:11:14] You must broaden your team.\\n[1:11:19] Now, if we look at sort of\\nthe Renaissance Developer\\n[1:11:23] throughout the stock, I've\\ncalled them they different ways.\\n[1:11:28] I think you need to be\\ncurious and keep learning.\\n[1:11:34] Think in systems, communicate\\nwith precision, be an owner.\\n[1:11:43] If you build it, you own it.\\n[1:11:46] And finally, become a polymath,\\nexpand your knowledge.\\n[1:11:52] Then, you'll have plenty of time next week\\n[1:11:54] to start putting all\\nof this into practice.\\n[1:11:58] Before tonight, join me at the\\nLas Vegas Festival Grounds.\\n[1:12:05] There'll be great food, some crazy games,\\n[1:12:08] and, of course, live music\\nheadline by Beck and Kaskade.\\n[1:12:12] And it's a chance to celebrate\\nwith your teams and unwind\\n[1:12:18] after a week of serious\\nlearning and building.\\n[1:12:23] Now, there's one more thing.\\n[1:12:31] I want you to leave you with this.\\n[1:12:33] When you build something like an app,\\n[1:12:37] do customers ever thought\\nabout all the work\\n[1:12:42] that goes underneath there?\\n[1:12:45] An Amazon customer will click a button\\n[1:12:48] and the package arrives.\\n[1:12:50] Does it think about the people\\n[1:12:52] that actually maintain the catalog,\\n[1:12:57] that do the supply chain?\\n[1:12:59] All of that work, nobody sees that, yeah?\\n[1:13:04] Your customers are never going to tell you\\n[1:13:08] that your database engineers\\nare doing amazing work\\n[1:13:11] and they love what they've done.\\n[1:13:13] Only you understand that\\nwork that goes into it.\\n[1:13:21] I believe it is important for all of us\\n[1:13:26] to have pride in our work,\\n[1:13:29] in the unseen systems that\\nstay up for the night,\\n[1:13:33] in clean deployments, the\\nrollbacks that nobody notices.\\n[1:13:38] Most of what we built,\\nnobody will ever see.\\n[1:13:44] And the only reason why we do this well\\n[1:13:48] is our own professional pride\\nin operational excellence.\\n[1:13:55] That is what defines the best builders.\\n[1:13:58] They do the things properly,\\neven when nobody's watching.\\n[1:14:06] And when I look at the work\\nthat you deliver every day,\\n[1:14:11] I see that commitment everywhere.\\n[1:14:15] So for that, I am immensely proud of you.\\n[1:14:22] Thank you for all that you do.\\n[1:14:26] Two more.\\n[1:14:28] Oh.\\n[1:14:29] (audience clapping and cheering)\\n[1:14:48] Two more words.\\n[1:14:50] Werner out.\\n[1:14:52] (remote clatters)\\n[1:14:52] (audience clapping and cheering)\\n[1:14:56] (bright music)\\n[1:15:26] (bright music continues)\\n[1:15:56] (bright music continues)\\n\", \"stderr\": \"\", \"needs_credentials\": false, \"needs_browser\": false}"
