https://www.listennotes.com/podcasts/chit-chat-stocks/the-future-of-artificial-3ylaqngtMR7/[00:00:00]intro: Welcome to Chitchat Stocks on this show host Ryan Henderson and Brett Schaefer analyze businesses and riff on the world of investing. As a quick reminder, Chitchat Stocks is a CCM media group podcast. Anything discussed on Chitchat Stocks by Ryan, Brett, or any other podcast guest is not formal advice or recommendation.intro: Now, please enjoy this episode.Brett: Welcome in. We have another episode of the Chitchat Stocks podcast for you this week. We have a fantastic interview coming up with Shawn Wang from LatentSpace. It is a, I'll say covering anything AI. A lot of the stuff, you know, for me and Ryan, it might be going over our heads and it might be a little too hard technically for us, but that's what we brought on Shawn to the show today.Brett: For a lot of public market investors, this new [00:01:00] AI stuff, it's hard to You know, see what is, what is working, what's just a narrative, what all the stuff that's getting thrown at us during this boom times. So Shawn, we wanted to bring you back on the show. You came on, I think almost exactly two years ago now to talk more cloud stuff.Brett: Now we're really going to talk about cloud AI and how it is impacting the startup ecosystem. So Shawn, as we kick off the show. What is your relevant expertise in this booming AI field? swyx: Oh God, that's the million dollar question here. So I am so for, for listeners who haven't heard back the previous episode that I was on I was finance and public markets guy.swyx: And I was, I was in a hedge fund for my first career. And then I changed careers to tech where I worked at AWS and three unicorn Sort of developer tooling cloud startups. My relevant expertise is you know, on, on some [00:02:00] level, I, I'm just a software engineer that is building with AI now. And then on another level, I had, I actually, when I was an options trader back in the sales side, I actually did a lot of natural language processing of the Bloomberg chats.swyx: So I fed all of the Bloomberg chats into a pricing mechanism. Then built our global pricer. So our entire options desk was running off of that thing. This was about 13 years ago. So so you know, I, I've always had some involvement with like AI, but like, you know, it was never a big part of my identity and I think.swyx: The more foundation models came into focus, and foundation models is a very special term as opposed to traditional, maybe machine learning finance that a lot of your listeners might be familiar with then you start to build differently, and there the traditional software engineering skills become a lot more relevant.swyx: So relevant expertise now is that I, I guess I've sort of popularized and created the term of AI engineer, which you can talk about and created the industry such that Gartner now considers, considers [00:03:00] it like the peak of its hype right now. And I, I consider that both a point of success and also a challenge because I have to prove Gartner wrong that it has not peaked, but you know, they put us at the top of the hype cycle, which is kind of funny.swyx: Because I started it, so. Ryan: Yeah, it's it's a unique challenge but yeah, funny anecdote. Okay, so a lot has changed since we last spoke. Yeah. Pretty much this whole world of AI that everyone's talking about now or at least has become mainstream has, I believe that kind of kicked off right after the discussion or our last discussion.Ryan: So I guess the last discussion was really focused on the cloud computing industry broadly. And that was actually right around the time when AWS. Azure, GCP all the revenue growth rates were coming down and actually now with the hindsight bottoming. So my question for you is what has, I guess, [00:04:00] what has changed over the last two years and why has revenue growth at the big cloud providers re accelerated?swyx: Yeah, again, like, revenue growth at big cloud providers is due to factors that, you know, probably I don't have a full appreciation of. I also challenge the fact, the idea that everything has changed. You know, I think in some ways, this is just like the next wave of something that was just a broader, maybe like 20, 30 year long trend anyway.swyx: You know, we, we needed more cloud compute. Now we need even more cloud compute. Now we need more GPUs in the cloud instead of CPUs, right? Like, what's really changed? I don't know. Like, you know, people still want serverless everything. People still want orchestration. People still want you know, unlimited storage and bandwidth and all the sort of core components of cloud.swyx: In that sense, it hasn't really changed. I do think that if you see there are plots over time of the amount of money and flops invested in machine learning models, that actually used to follow a pretty log linear Moore's law type growth chart for the last like 40 years. [00:05:00] And then, You had 2022 happen and now everyone's like, oh, you can train foundation models now.swyx: And actually you've seen a big inflection upwards in the amounts that people are throwing in throwing the money in there just because they see the money now. So like every, it's like obvious to everyone, including us, including me in a way that it wasn't obvious to basically everyone, but Sam Altman and Satya Nadella circa 2019.swyx: Like they knew this. Four years five years ahead of everyone else. And that's why they went big on OpenAI. But now that we see this, obviously everyone's throwing money into NVIDIA, basically. Brett: I had, why, why are, and this is maybe a question I think I know, but I'd like the answer again, and it feels like it's maybe a basic question, but a lot of, I think listeners are going to want to kind of understand this connection.Brett: Why do these new AI companies require so much upfront spending? On NVIDIA chips, cloud computing costs. All that stuff. swyx: Yeah. I mean, so [00:06:00] you have to split it by whether you're a foundation model lab or you're basically everyone else that consumes foundation models. So the rough estimate for, let's say GPT 3 was like 50 million to a hundred million in compute for one run.swyx: And for every one successful final training run, maybe you have between a hundred to a thousand. Prior runs before that, right? So just pure R& D. The estimate for GPT 4 was 500 million. We've actually had two generations of frontier models since then, just for OpenAI. So that would be GPT 4. 0 and GPT those are the models that, those are only, only the models they've released.swyx: And also not, those are only the text models, we haven't counted the video models and all the other stuff. So it's just a lot of upfront investment, right? Like, I think it's, it's like the classic capital fixed costs upfront thing, where, you know, you have a pre training phase where you're just consuming all of the internet.swyx: [00:07:00] Data that's, you know, there's nuances to that, but we won't go into that. And, and, Alka, Alka comes the other end, you know, 3 to 6 months later, Alka comes a model that you then spend another 6 months fine tuning and red teaming, and post training, and then it's ready for release. So, like, so there...

https://podcast.scalingdevtools.com/episodes/swyx-2Plus, Shawn started the AI Engineer movement with his essay Rise of the AI Engineer and organized two incredible AI engineer conferences in the past twelve months - AI Engineer World's Fair and AI Engineer SummitAnd Shawn has angel invested in DevTools like Airbyte, Railway, Supabase, Replay.io, Stackblitz, Flutterflow, Fireworks.ai while running the DevTools angels community.Besides this, Shawn curates DX.tips (DevTools magazine) and in a past life wrote the Coding Career handbook, championed learn in public, cofounded Svelte Society and was previously Head of Developer Experience at Temporal, and a Developer Advocate at AWS and Netlify.Also, before this, Shawn had a very successful career in investment banking, trading, building data pipelines and performing quantitate portfolio management. I think this brings him a very unique perspective - I've always admired his ability to zoom out and see the big picture and the trends.Even though Shawn is now all-in on AI, he's still one of the go-to authorities on DevTools go-to-market.As you can tell, Shawn is someone I deeply admire.

I also mentioned some other things that I've found in the different roles in the category: Bottoms-up and open source have been very challenging in the growing a company success criteria. That's what different roles focus on: bottoms-up and open source, and particularly open source. You don't have to be open source.

revived by https://www.swyx.io/how-to-find-podcasts-that-have-been-deletedhttps://softwareengineeringdaily.com/2019/12/19/no-code-with-shawn-wang/The software category known as “no-code” describes a set of tools that can be used to build software without writing large amounts of code in a programming language.No-code tools use visual interfaces such as spreadsheets and web based drag-and-drop systems. In previous shows, we have covered some of the prominent no-code products such as Airtable, Webflow, and Bubble. It is clear that no-code tools can be used to build core software infrastructure in a manner that is more abstract than the typical software engineering model of writing code.No-code tools do not solve everything. You can’t use a no-code tool to build a high performance distributed database, or a real-time multiplayer video game. But they are certainly useful for building internal tools and basic CRUD applications.We know that no-code tools can create value. But how do they fit into the overall workflow of a software company? How should teams be arranged now that knowledge workers can build certain kinds of software without writing code? And how should no-code systems interface with the monoliths, microservices, and APIs that we have building for years?Shawn Wang is an engineer with Netlify, a cloud provider that is focused on delivering high-quality development and deployment experience. Netlify is not a no-code platform, but Shawn has explored and written about the potential of no-code systems. Since he comes from a code-heavy background, he is well-positioned to give a realistic perspective on how no-code systems might evolve to play a role in the typical software development lifecycle.

https://podcasts.mongodb.com/public/115/The-MongoDB-Podcast-b02cf624/f96bd55fTranscriptMichael Lynn: Welcome to the show. My name is Michael Lynn and this is the MongoDB Podcast. Thanks for joining us. Today on the show, Lena Smart, Chief Security Officer of MongoDB, and I team up to interview Dwight Merriman, co- founder and key contributor to MongoDB. Dwight Merriman is a true tech legend. In addition to co- founding and co- creating the MongoDB database and 10gen now called MongoDB, the company. He also co- founded and led several other well known successful companies including Business Insider, DoubleClick and Gilt Groupe. In today's interview, Dwight shares openly and honestly about the motivations behind creating the database, which now actually claims nearly half of the entire NoSQL market. He talks about the decision to build the database rather than use something that existed at the time. Dwight's friendly, easy to talk to, knowledgeable, and probably one of the smartest individuals that I've had the pleasure of chatting with. Without further ado, let's get to the interview. If you enjoy the content, please consider visiting Apple Podcasts or Spotify. Leave a rating and a comment if you're able, let us know what you think. Stay tuned. Hey, did you know that MongoDB University has been completely redesigned? That's right. Hands- on labs, quizzes, study guides and materials, bite- sized video lectures, programming language specific courses. You can learn MongoDB in the programming language of your choice, Node. js, Python, C#, Java, so many more. You can earn that MongoDB certification by validating your skills and leveling up your career. Visit learn. mongodb. com today.Lena Smart: So it is my absolute pleasure, and I'm so glad that you could make it in person today, to introduce Dwight Merriman. He is the first CEO of MongoDB, and you were still coding, I understand. You're also co- founder and director of MongoDB as of today. Are you still coding?Dwight Merriman: I'm still coding or tinkering a bit myself, but not on the database anymore. I think there's, to really dive in and work on it, there's a certain minimum number of hours a week you have to work on it, just to keep up with the code base and the state of everything, because it's not short, it's not a small program anymore.Lena Smart: Amazing. And also in the room we have Mike Lynn, who's our developer advocate, and I know that you'll likely have some questions.Michael Lynn: Yeah, for sure.Lena Smart: And just fire ahead, because probably this will be the most interesting person I'll speak to in a inaudible too.Michael Lynn: Well I'm fascinated already and I've got so many questions for Dwight, but I'm going to let you go ahead and ask away.Lena Smart: Cool. So the first question I have, and this has been a burning question of mine since I joined three and a half years ago, is how did you start the company? How did you start MongoDB?Dwight Merriman: Right, so when we started, actually the name of the company was 10gen, and this was around 2008, or I forget the date, maybe two months before that, I can't remember. The original, what we were really looking at, at the time, is as myself and our other co- founders like Elliot and Kevin, we've been working on various entrepreneurial projects, and we were seeing this repeated pattern where over and over. New product idea, you start building the system. At this point, I've been doing that for quite a long time. So knew what the best practices were at the time. But it was always around that timeframe, January, 2008, whenever it was, it just seemed like it was always a bit awkward. There was awkward and un- anesthetic, and it just seemed like there was a lot of duct tape and rubber bands. And even though those were best practices. You would talk to CTOs at the time, and they would say things like, " Putting memcached in front of databases is okay, and roll your own sharding in front of my MySQL sequel or Postgres is okay, but it isn't. It was because there wasn't a better way at the time. And everything, that was really when the cloud computing EC2 was really taking off. So it was very clear to us that cloud computing was the future, and a lot of the traditional products weren't very cloud- friendly. So if you have a database that scales vertically, so I can make it bigger, but then it's a mainframe, or a Sun 6500 or something like that, that's the opposite of a cloud principle, which is horizontal scalability and elasticity. And then if you tried to do it the other way, horizontally, it was usually rolling your own when it came to operational databases. And a lot of other things, but also just agile development was the way to go then, all iterative development. But a lot of the old tools, and this isn't just databases, but languages, everything, weren't really designed for that, because they were invented earlier. So it's not their fault. So we were just saying, " Gee, there's got to be a better way to develop applications," and this is both on the how to develop them, how to code them, and also on how to scale them, and how to run them in the cloud painlessly. So our first concept was just we were going to do platform as a service. So we were going to try to do a fresh take on the developer stack, versus LAMP and whatever else was common then. And see what we could come up with. So we started building a platform as a service system. It was open source and this was very early. So I think when we went to beta, it was almost exactly the same time that Google's, was it Google App Engine?Lena Smart: Yeah.Dwight Merriman: It's the same time it came out to beta. So our timing was, it was like when they came out with it. And I was like, "Oh, okay, somebody there's thinking similar thoughts." And so that was fine. But a few months later, as we got a little further into it, I was thinking about it and I was like, I'm looking at things like AWS, where they have all these microservices. And they're like, " I'm not going to give you a full cloud platform. I'm going to give you some building box for your toolbox, and over time I'll give you more." Because the scope is large, so today they have a lot of services, but this, we're 15 years later- ish. So if I give you a platform though, to give you everything you need really, it's a big scope, and it's going to take quite a while to build it. So I think platform as a service makes sense, but we got further into it, and we had something working analogous to Google App Engine, or I guess, Heroku was around back then. It just felt like, " Boy, to get this true maturity, there's so many pieces that you would want in it. It's going to take a long time. This is, it's going to take a decade or something." And for a startup you only have so much runway. And it's now even today platform as a service, I think, is a valid notion and concept, but it's certainly not mature yet. The more AWS style or microservices- style approach, which you could do on all the big cloud platforms today, I just, I say AWS because I'm just contrasting it with the PaaS vendors back in the day, approach is still the dominant approach. So we've been building this, and really what were we building? So we're trying to build something where you'd write some code, you put it in inaudible, then you would just click Deploy. And it would deploy your app into our system in the cloud, try to handle scaling for you, including things like app server layer, app tier, how many app servers should there be, and low balancing for that....
