I stood at this pool, at both monuments and saw both reflections… He’s a God damn idiot, as are the fools that support him. The “Reflection Pool” wasn’t designed by American architect Henry Bacon a hundred years ago to look like a swimming pool. It’s designed to have a darkened characteristics that has reflective qualities to reflect the monuments. That way, the Washington Monument is reflective to you when at the Lincoln Memorial, and when at the Washington Monument, the Lincoln Memorial is reflective to you. It’s designed to enhance the grandeur of monuments, create an illusion of reflection, and inclusion of expansive space of unity. He’s a tacky vulgar person that vulgarizes everything he touches. America isn’t becoming great, it’s becoming vulgar. Credit - Mathew Reed

@insane_analyst I’ve made this argument for decades for different semis without success. In the end public executives and investors value margin more than margin dollars. Fair warning.

Bro do you even book value? HBM post in progress. To the retards who think I am bearish memory, do you think semis world want X GB of capacity at 80% gross margins or 3X GB of capacity at 60% GM? Everyone wins in second scenario. HBM is a mistake and you all too retarded.

If MTK TPU succeeds, SMTC is a 2-4x from here. If MTK TPU fails, SMTC is a 1.5-2x from here. SMTC CTLE can give 4-7 dB SNR gain. ~300G SerDes at PAM6 has 4-5 dB SNR penalty from theory. MTK would need 2-4 dB improvement in design + CPC + SMTC CTLE + good EMIB pkg to make it.

From some discussions we came across today on TPU v9 networking, the direction seems broadly consistent with what we had touched on in our earlier report. The next step-up in Google's TPU networking bandwidth appears to come from two directions. First, the new scale-out network architecture, which seems to be increasingly corroborated by the Boardfly direction and Virgo Network. Second, the continued upgrades in scale-up / ICI bandwidth. We had also flagged the possibility that future TPU systems could move toward a higher-dimensional torus topology, potentially a 6D torus. If TPU v9 upgrades the topology, optical module speed, and port ratio at the same time, a roughly 4x increase in ICI bandwidth versus TPU v8 may not be entirely out of reach. This is likely not just a matter of "buying more optical modules." It could reflect a system-level architecture shift in Google's TPU roadmap toward higher bandwidth and higher optical interconnect content. One point that did not get much airtime in today's discussion, but which we had spent more time on in our earlier report, is the potential introduction of coherent-lite technology. If coherent optics does make its way into this part of the architecture, the dollar content per optical module could rise meaningfully — in some designs, perhaps even close to doubling. It would also bring in a more complex modulation stack, which may call for more advanced silicon photonics, thin-film lithium niobate, or other higher-end PIC platforms. That matters because the value migration would not be limited to the module layer. It could also benefit upstream components, including lasers, modulators, PICs, DSPs, connectors, and advanced packaging. If this plays out, the TPU networking upgrade would meaningfully shift more AI cluster value into optical and connectivity content. Names we'd keep an eye on as potential beneficiaries include $LITE , $COHR , InnoLight, $NOK , $MRVL , $SMTC , $AXTI , and $TSEM .

Deep|AI Infra 2026: Shifting from "Brain Power" Competition to "Whole-Body" Evolution This is one of our most important reports this year, and our entire team invested a significant amount of time and effort into it. We observed that the OCS ratio in Scale Up scenarios is still rising rapidly, and we also found that $MRVL is involved not only in TPU but also in LPU. In 2026, the focus of AI development has pivoted from chasing high benchmark scores to pursuing AI Agents capable of multi-step reasoning and autonomous action. This infrastructure arms race is undergoing a transformation akin to biological evolution. If an AI system is viewed as an evolving organism: the GPU/TPU represents the calculating brain; Memory and Storage serve as the memory carriers for experience and context; the CPU acts as the hands coordinating tasks; while Optics and Networking function as the limbs supporting systemic data flow and response sensitivity. Under the framework of the Agent Scaling Law, the core bottleneck is no longer just the FLOPS of a single chip (brain power), but rather the communication efficiency (limbs), the memory wall (memory), and the Total Cost of Ownership (TCO). The “Brain” Idle Crisis: Even with the most powerful compute cores, if the “limbs” (communication) are underdeveloped, chips will sit idle for over 1/3 of the time waiting for data. The “Memory” Retrieval Bottleneck: Long-sequence reasoning for Agents imposes rigorous demands on KV Cache management; the performance of memory and storage components has become the deciding factor for an Agent’s logical depth. Dimensional Evolution of “Limbs”: To overcome the communication bottlenecks inherent in MoE architectures, infrastructure is moving from 3D Torus toward high-dimensional topologies (up to 10D). Networking investment weight is now matching or even surpassing that of compute chips. This report outlines the bottlenecks facing AI Agents and recent TPU progress, specifically exploring how Google TPU optimizes “whole-body” coordination through vertical integration. We argue that: Networking is the new core battlefield: To solve MoE All-to-All bottlenecks, Google is significantly expanding scale-out bandwidth and shifting from 3D Torus to higher dimensions. Unlocking TCO and Allocation Efficiency: Through proprietary architecture and vertical integration, the TPU v7 rack cost is significantly lower than the NVIDIA GB200. This efficiency gain frees up CapEx for growth in optical communications and memory. $LITE $NOK $CRDO Detailed Report fundaai.substack.com/p/deepai-infra…

We've released our first CPO forecast based on ELSFP shipments. We aren't late. In the infamous words of Google's Hong Liu and others - CPO is a technology that is always arriving in N+2 years, where N is the current year.

One of the things Musk vs Altman shows is how much more promising AI is than anyone expected. Sam could have started it as a for-profit company. His life would be much simpler now if he had. But he didn't realize in 2015 that AI would warrant more than you can raise in donations.

Research| $LITE : From Cyclical Optical Name to AI Datacenter Bottleneck LITE rallied today, and on the surface it looks like passive flows tied to the Nasdaq-100 inclusion. But the real story runs deeper. Last week’s print already validated the demand intensity in 1.6T, InP/EML, and OCS — revenue, gross margin, and operating leverage all started to come through. So today’s index flow is more of an catalyst; the substance is that the market is beginning to reprice LITE from a legacy optical components cycle stock into a critical bottleneck asset in AI datacenter optical interconnect. In China, Innolight’s investor communication today flagged 2.4T and coherent-lite, and that signal is worth paying attention to. The market is no longer just trading the 1.6T ramp — it is already looking ahead to the next-gen architecture. 2.4T / coherent-lite is not a simple bandwidth upgrade: it implies higher lane rates, more complex modulation schemes, longer-reach links, and substantially higher photonic-electronic integration requirements. The higher the technology bar, the better positioned the names with real depth in EML, InP, laser, and OCS/CPO — namely LITE and COHR. We flagged this technology direction two months ago.

The sharp rally in $LITE and other optics names today was driven not only by QQQ 100 inclusion, but also, importantly, by Innolight mentioning 2.4T demand in their group call. We highlighted the 2.4T timeline in our most important TPU Report last month. We'll be publishing a quick take on this shortly.

I failed the final exam of my first undergrad upper division analog design class but dammit its time for redemption. That class led to 50 hour weeks JUST FOR THAT CLASS, mostly locked in a lab with no windows.

Power semis is 100% the most asymmetric information play right now. It’s 100% coming. $NVDA requirements are immutable but nobody has a fucking clue. I cannot wait for @insane_analyst first principles deep dive demo results. I don’t think people realize this has to ship late 2026 for rubin ultra - I think.

Im wondering if long memory short Qualcomm is worth sizing huge. Like 20%+ position. I think high end smartphone is also gona hit 30% demand destruction minimum by H2. Gona buy a $20 replacement battery kit for my S23 ultra. Great phone, degraded battery. Need to sleep.
