    Episode 11: AI competition with Alibaba and Huawei

    This week, I welcomed back Glenn Luk as well talked about the recent happenings with respect to Alibaba’s Great Leap Forward in its AI ecosystem, cloud platform and the full stack solution. We talked about over how Alibaba has gotten back into the good graces of Chinese government and did all the hard work of becoming a powerhouse in AI. They are basically the only hyperscaler outside of Google who is doing its own models, AI apps, AI servers, chips and cloud solutions. AI is a central part of Alibaba’s strategy in winning the global cloud competition. It is now making great progress in rest of the world as seen by its major data center expansion strategy in 2025 and 2026. We also talked about how Huawei and Ascend have caught up in the AI chip race by coming up with whole system approach which takes advantage of Huawei’s core competency in networking and software integration with hardware. It seems to us that many people are missing the full picture when only comparing the chips rather than the full system. Please listen in as we explore global AI race and more.

    Episode 10 - A view from Brazil

    On this episode, I spoke with my friend Nelson, who is a Brazilian journalist currently living in and reporting from Beijing. We talked about how China and Brazil’s relationship has grown in the past 15 years. How Brazil and America’s relationship has been declining, especially under Trump. And we talked about what are the things going forward that will likely to continue to pull the 2 countries together. Did you know that ByteDance CEO just met with Lula to build a $10B data center in Brazil or that Huawei has just restarted selling phones in Brazil? This is after Alibaba and Huawei are both investing in new data centers for their cloud in Brazil. Did you also know that China is very involved with building infrastructure in Brazil? Recently, it is in discussion with Brazil to build a Bioceanic Corridor from Peru to Brazil’s Atlantic Coast. This is a public episode.

    Episode 8: Han Feizi on China

    This week, I’m happy to welcome Han Feizi on my show. He is a writer on Asiatimes and has very interesting and high quality view on China’s economy and its changes over time. Since I recently stayed in Beijing for 3 weeks, it was good to catch up with him just on what I saw and how it matches up with what he sees on the ground. One thing that Han really emphasizes is that China’s economy is actually a lot larger than US’s economy. In fact, it is not at all dependent on export, because China specifically does not report on activity of certain service sectors as part of economy. As such, trade war doesn’t really do much to most of China’s regions. The chart above would just show how much of China’s production for each industries is actually dependent on US export. You can see that Consumer Electronics is basically the only major one. Of course, a large part of that is just Apple exporting products made in China to America and then making a huge profit on top.

    Episode 9: Initial thoughts on 9/3 Parade

    In this episode, I am joined by Lei and Bora to discuss all the various interesting platforms that we saw in the recent parade. We didn’t talk about the political/geopolitical side of things since that’s really not interesting. We also didn’t talk about nukes, since that’s just a distraction. So, we really focused on which platforms on game changing and we they are important. I think we spent the most times on YJ-19 and the UUVs (AJX002 & HSU100) + Underwater implications: We also took a serious look at the various UCAVs on display, especially from just the huge # of highly capable large drones that seem to already be in Western China for tactical and conceptual development of MUMT and unmanned air warfare. And the last one we really spent a lot of time on were the laser platforms and just the huge implications as they keep getting more capable over time. Of course, I also talked about the coolness of seeing all the new EV related tech that was showcased in the Type 100 tank and FSV, but that’s not as transformational as the other stuff we saw.

    Episode 7: Thoughts from my China Trip

    This episode, Lei joins me as we discuss the things that I encountered during my trip to China, where I had a lot of thoughts about the overall economic situation, the current tech scene and development socially since the last time I was there. For me, there were a lot of surprises, especially in the second and third tier cities. A common refrain I hear from parents in their 40s is the concern that their kids won’t do better than them, because of the involution culture. But in a world where developed country are facing declining lifestyles, is it reasonable for Chinese people to expect every generation to outperform the previous one? This is a public episode.

    Episode 6: AI Q&A

    This week, I decided to do a Q&A of AI related questions I have received on substack, Twitter, discord and forum. Open source models running on domestic AI chip. New way of measuring from Stepfun. I talked about AI robots, AI applications in industries and running AI on different type of chips. I will have more on China and AI once I get back from my China trip. The way that AI is incorporated into Chinese society since DeepSeek is something to behold. This is a public episode.

    Episode 5: AI infrastructure

    This week, I invited my friend Simon on the show to talk about AI infrastructure. This is a very interesting topic to think about. We talked about the reason for Nvidia’s market dominance and the problems that Intel and AMD have faced in developing their own market place. We talked about the number of chips involved and the challenges in building large data centers. Here is a chart of the Hopper deliveries for 2024. Keep in mind that Google also has their own TPU for inference. Here is a chart of Chinese Hyperscaler’s purchases of H20 in 2024. But keep in mind that they do rent compute from public/state built data centers that use smuggled in H100/H200 as well as Ascend chips. Here is the deliveries of H100/H800 in 2023. So if we just consider the Hopper deliveries from 2023 and 2024, the American hyperscalers have quite the computation advantage over Chinese hyperscalers. Although, the gap is much smaller if we factor in all the smuggled in chips. As I’ve discussed before, China had them everywhere to the point where they were sitting idle in many cases. I also asked Simon about the amount of chips needed to do inference. How was Tencent able to have enough compute for 8 million DeepSeek R1 requests at the same time with much less compute than what Google had. He sent me this chart of where the results improve logarithmically in compute for reasoning. So if you look at green line, going from 4 generations to 16 generations improved accuracy by about 15% and then going from 16 generations to 64 generations improved the result by another 5%. If we look at Google search results, they appear to be giving progressively better AI results on top. That is likely from running through and generation more tokens on their reasoning models. So you can choose to serve 8 million prompts at same time with vastly less compute, but you will also have inferior results. although you will also reach diminishing returns pretty soon. Here is a chart of rental cost from various Nvidia chips in China. Despite the increased demand for inference post DeepSeek, the cost of all Nvidia rental cost continue to drop, so they are likely not facing a crunch for computation yet. This is a public episode.

    Episode 4

    I was inspired to make an episode on manufacturing and why it is difficult to do manufacturing in America after I watched this video, I asked Lei to join me to discuss how China has taken over the expertise on manufacturing all the “basic stuff” Of course, China has now developed the ability to manufacture higher end stuff and increasingly designing its own products. But China’s upstream supply chain dominance is something that’s not well understood. So in this episode, we went over our experience with manufacturing and supply chain. Lei is more familiar with this than me, so he did most of the talking. This is a public episode.

    Episode 3: China's High Speed Rail

    For the third episode, I invite Glenn Luk onto the show to talk China’s vast HSR. He helped us debunk many of the myths regarding China’s HSR economics. We also talked about how HSR helps facilitate travel, improve Quality of Life and increase freight inside China. Here is a look at the current Chinese high speed rail map And its overall railway map. Very well connected and you can imagine that many lines end up in more remote areas that cannot justify the expense of building HSR. Even so, they are still likely faster than the 70km/h train that I used to take growing up. This is a public episode.

    Episode 2: Russian/Ukraine conflict

    This week, I welcomed Snek onto my podcast to talk about his thoughts on the ongoing Russian/Ukraine conflict. This is an area that I have not followed closely, but Snek is very well versed in. We recorded with lower volume, so raise the volume to hear it clearly. We look at the conflict in 3 areas: * The current state of the conflict. * The usage of drones and AI in this conflict * The industrial aspect of this conflict and why US/Europe’s military industrial complex have struggled keeping up. Although this veers off my usual focus on Chinese tech, I think this conflict does have significant implications on 2 of the areas that I really enjoy looking into: drones and industrial capacity. As a follow up, Snek pointed me to this article: Pentagon only has 1/4 of the Patriot missiles it needs. Ukraine and the Middle East have consumed all of this. America is seriously running low on this stuff and it will likely burn up even more over the continued conflicts. On the topic of longer ranged attack drones and their motor. You can see just how cheap China has gotten down the cost of micro turbojet. I’d imagine all the low cost long range drones or missiles around the world are made with these engines.
