Quotes Charna Parkey "For any developer who has sort of avoided the soft skills, the managerial skills, et cetera, you should go listen to some of those courses. You are now going to be managing this AI workforce that you really do need to treat like a team of interns that you're delegating work to, that you're giving feedback on, and all of those skills of sort of like more senior-level engineering of design reviews, code reviews, feedback, like that's gonna be more central than actually writing a line of code yourself." Rodrigo Nader "We're going to see millions and millions more agents than humans very soon, right? So we don't think that these agents are going to emerge from, one, only developers, meaning like hard-code developers, neither from big companies creating solutions that will suddenly solve all the problems."

From energy bottlenecks to proprietary GPU ecosystems, the CEO of TensorWave, Darrick Horton explains why today’s AI scale is unsustainable—and how open-source hardware, smarter networking, and nuclear power could be the fix. QUOTES Darrick Horton “The energy crisis is getting worse every day. It’s very hard to find data center capacity—especially capacity that can scale. Five years ago, 10 or 20 megawatts was considered state-of-the-art. Now, 20 is nothing. The real hyperscale AI players are looking at 100 megawatts minimum, going into the gigawatt territory. That’s more than many cities combined just to power one cluster.” Charna Parkey “We’re still training models in a very brute-force way—throwing the biggest datasets possible at the problem and hoping something useful emerges. That’s not sustainable. At some point, we have to shift toward smarter, more intentional training methods. We can’t afford to be wasteful at this scale.” TIMESTAMPS [00:00:00] Introduction [00:01:00] Founding TensorWave [00:04:00] AMD as a Viable Alternative [00:08:00] Open Source as a Startup Enabler [00:09:30] Launching ScalarLM [00:12:00] ScalarLM Impact and Reception [00:14:30] Roadmap for 2025 [00:16:00] Technical Advantages of AMD [00:18:00] Emerging Open Source Infrastructure [00:20:00] Broader Societal Issues AI Must Address [00:22:00] AI’s Impact on Global Energy [00:26:00] Fundamental Hardware vs. Human Efficiency [00:30:00] Data Center Density Evolution [00:34:00] Advice to Founders and Tech Trends [00:38:00] AI Energy Challenges [00:44:00] AI’s Rapid Impact vs. Internet [00:46:00] Monopoly vs. Democratization in AI [00:50:00] Close to Season Wrap Discussion and Predictions

So which one are you wanting to do, misrepresent them or just completely leave them behind from this technical revolution?" Anastasia: "The real issue now is that the lack of diversity in the current AI labs leads to the situation where all LLMs look alike." Anastasia: "Being able to design, to find, and also to create the appropriate data mix for large language models is something that we shouldn't really forget about when we talk about the success of what large language models are."

[...] This democratization — if you don’t know how to use it — it’s not doing its job.” KEVIN CARTER “Those scrappy startups are going to be the ones that solve it. They’re going to figure out new and interesting ways to leverage instructions. [...] You’re going to see a push from them into the hardware manufacturers to enhance workloads on FPGAs, leveraging AVX 512 instruction sets that are historically on CPU silicon, not on a GPU.”

In this episode of Open Source Data, Charna Parkey interviews Pete Pachal, founder of The Media Copilot. With over two decades of experience covering technology, Pete shares his insights on how AI is transforming media, journalism and discusses  how journalists can embrace AI as a tool to enhance their work to adapt and thrive in this new environment.  QUOTES PETE PACHAL: AI is something that you control. I know, it feels like it's a wave that's coming over that it's unstoppable, inevitable. And that's true to a large extent. But at the same time, it's not, there's no there, right? There's no spark, there's no intent. (...) Never relinquish your role as the ultimate creator and person responsible for what's coming out of this thing. CHARNA PARKEY: I think that there was a point where I found myself shifting more away from media and towards individual curated newsletters because like subject matter experts in that area, I could be like maybe they're going to summarize it incorrectly, et cetera. But at least I know my theory of mind of that individual. And then when I expand that to media, I don't know who's writing what and who's shadow writing what for who.
