Statements from this episode (23)
AI does not make functional domain expertise obsolete, Stone argues
“So I don't think it makes the functional expertise obsolete. I think it means that teams have to be more comfortable with maybe this helps us move faster in a certain direction.”
AI lets PMs and designers build further before needing engineering help
“I have found that PMs, designers, data scientists are able to get farther in the product development life cycle before engineering really needs to be front of the line in unlocking things than was true a couple years ago.”
AI unlocks decades of historical experimentation data for Netflix teams
“So instead of that needing to be only the experts who were here for 20 years and saw every experiment or know where to find it, we're now able to do that faster within product and tech across all functions. And a big unlock for us is our business stakeholders …”
Core disciplines retain distinct advantages in problem framing and architecture
“Data scientists are still going to be experts at Can we trust this data? Are we interpreting it the right way? What's the data versus judgment that we should be applying here? A product manager is still going to be exceptional at saying, have we really framed …”
Elite engineering, data science, and creativity remain scarce despite AI
“I still find great engineering to be scarce, great data science to be scarce, great creativity to be scarce. So I, yes, some things are easier, but that hasn't dissolved in my mind.”
AI agents make standardized infrastructure and paved paths essential for guardrails
“In a world of AI with agents operating across multiple systems, wanting source of truth data, the importance of having preferred paved paths that get the most of the benefits and produce some guardrails so we can make sure we're doing good work, common infrast…”
Netflix engineering hiring prioritizes systems thinking over local domain expertise
“That means that engineering profiles are more distributed systems, more infrastructure, more of that system thinking mindset than a local business expertise.”
Netflix envisions future work being jointly performed by humans and AI
“One of the visions we have at Netflix is we will have so many agents that are contributing to doing work. That you need to be able to reason and rationalize throughout that. You know, the humans are the ones guiding what's the problem we need to solve. Do I fe…”
Squeezing out deep design expertise for AI coding speed harms products
“But I think it would be a mistake to say design and deep design expertise in thinking gets squeezed out just because we can write Code faster. We can do data analysis faster. That feels like at least for a large scale consumer product like Netflix, I feel like…”
Netflix now seeks adaptable generalists over narrow specialists for most roles
“The days of very narrow, deep specialization feel more limited to me. I can come up with examples where we still need it because there's an industry or technology expertise where there's only a few people in the world who really know how things work. We have e…”
Cultivate systems thinking by zooming out one level from immediate tasks
“You don't have to boil the whole ocean. You don't have to solve for Netflix's overall strategy and who are we relative to competition, but you take the thing you're responsible for and you just do one zoom out. Of the problem you're solving and question that. …”
Systems thinking means prioritizing the broader organization over local optimization
“Do the thing that is right for the broader organization instead of just what's right for you locally. That's systems thinking as well. So it's not just seniority, but it's breadth of the way I solve this problem and I build this. Is it going to be useful to my…”
Netflix overlays company-wide AI fluency expectations instead of altering level ladders
“The way we've approached this so far is instead of trying to articulate at each level, Exactly how AI changes those expectations to instead put an overlay across all of the talent at Netflix, people on the team and those who are hiring to talk about an aspirat…”
Netflix now allows engineering candidates to use AI tools during interviews
“And even for things like coding interviews, allowing candidates, of course, to use AI tools, because that's gonna be part of what the work requires now.”
Netflix recently acquired Ben Affleck's AI post-production startup, Inner Positive
“So we recently acquired a company, Inner Positive, that was started by Ben Affleck, that built a set of models and capabilities that allow you, after you've shot something, to relight, reframe, reshoot, change dialogue in ways that are very impactful to get hi…”
High talent density is a prerequisite for confident, decentralized decision-making
“Well, the talent density is the non-negotiable. You have to start with that. If you don't have that, you can't get to a place where you have confidence in decision-making at all levels of the organization.”
Adding process to fix difficult planning wastes time without improving outcomes
“Every time we saw that and we added more process, we spent more time without getting better outcomes. And so it's another unnatural thing that I think everyone's inclination when things are hard and complicated is you think you're simplifying the problem by pu…”
Netflix uses its famous Keeper Test equally for positive performance recognition
“It's often cited in a way where you think of keepers test as that moment where you decide to let someone go, that they're not the right fit for the role and the conversation about that. But it's equally commonly used to have a conversation about how extraordin…”
Scaling organizations naturally drift away from talent density without constant diligence
“All of these things are not things that human beings or organizations at scale. Tend to do. So it's constant diligence to try to maintain the thing that's made Netflix a special place. Cause in the end, it's the work and the culture that attracts people and re…”
Netflix has not suffered a talent drain to AI frontier labs
“I don't feel like we've suffered or like other companies are vacuuming up all the good people because so many of them I do think sit at Netflix.”
Netflix continues to prioritize hiring junior talent and new graduates
“We are still hiring junior people, and they're really important to our talent strategy. So we still have an intern program. We still have a new grad program, which is, was new for us as of a few years ago. So prior to a few years ago, we were only hiring more …”
Software engineering will evolve to fluently guide and evaluate AI agents
“So I think engineering over time will evolve to. Be comfortable with that and have fluency in it and know how to guide new tech and agents and new capabilities to make sure that we feel really good about what the output is.”
Netflix will not mandate AI, allowing filmmakers to opt out entirely
“Netflix's role in this is to enable creators with whatever tools they want to use to bring their vision to life. There are going to be some creators or filmmakers who are on the end of the spectrum that says, absolutely not. No AI. That is not how I do product…”
