มาเล่าต่อหลังสัมภาษณ์เสร็จ แล้วมีการต่อรองเงินเดือนกันบ้าง
จากที่เล่าไปตั้งแต่ต้นแล้ว ว่าช่วงเงินเดือนมันถูกกำหนดมาตั้งแต่ตอนอนุมัติ Head Count แล้วว่าอยู่ Job Band/Job Grade อะไร โดยมันก็มีช่วง min - max อยู่
โดยปกติ หาก Cand เรียกเงินที่อยู่ในช่วง min - max ส่วนใหญ่ HR
Morgan Stanley: Bearings
The Big Picture: Bearings as a Core Robotics Play
> Architecture-Agnostic Growth: Bearings offer a diversified way to invest in the robotics sector because they are required regardless of a robot's ultimate design or form factor.
> Massive Market Expansion: Morgan Stanley forecasts a massive ~300x growth in the robot bearings market through the year 2050.
> Low Risk of Obsolescence: Bearings face very low substitution, in-sourcing, or obsolescence risks—you simply cannot design moving machines around them.
> OpenAI Endorsement: In a recent Request for Proposal (RFP) for U.S.-based hardware manufacturing capacity, OpenAI listed precision bearings as 1 of 6 critical components in its robotics category.
Content Scales with Robot Complexity
> Bearings 101: Every single motor in a robot requires at least one or more bearings to reduce friction and support rotating parts.
> Degrees of Freedom (DoF): As robots get more complex, the number of bearings multiplies.
Small quadcopter drone: Requires 8–12 bearings.
Humanoid robot: Requires 70 or more bearings.
> Pricing Variability: Depending on the specific use-case, individual bearings can range from under $1 to as much as $100
Global Bearings Market Dynamics
> Consolidated Supply: The top 6 global manufacturers control over 50% of the global roller market, with Chinese manufacturers making up about 25%.
> Current Demand Split: Roughly 40% of the overall market goes to industrial equipment OEMs, 30% to automotive, and 30 to distribution channels
Mirae Asset Securities: AI Bottleneck Issue
Power Bottleneck
> The Moment for Analog Semiconductors: The value of the analog domain, where Moore's Law does not apply, is exploding, giving suppliers overwhelming pricing power. Major players like TI, NXP, and Infineon are proving this dominant supplier market by executing synchronized price hikes in 2026.
> The Physics of 12,500 Amperes and 800V DC: In ultra-high-density AI racks of 600kW to 1MW, sticking to traditional 48V power distribution causes the current to skyrocket to 12,500A, making operations impossible due to heat loss. Therefore, shifting the architecture to 800V to reduce the current to 750A and cut copper requirements by 45% is a physical inevitability.
> Vertical Power Delivery (VPD): To prevent loss and voltage fluctuations during the "last inch" of stepping down to the GPU core voltage (around 0.7V), VPD—essentially the "CPO of the power world"—is emerging, which places the power converter directly beneath the GPU die.
Signal & Photonics Bottleneck
> Distance-Based Redistribution of Copper and Optics: The simplistic narrative that "optics will completely wipe out copper" is incorrect. A distance-based redistribution is intensifying, where copper and analog handle short distances (the scale-up domain) and optics take over long distances (rack-to-rack connectivity).
> Semtech’s Analog Magic: In 200G/lane high-speed communication, Semtech's technology is garnering massive attention by completely eliminating DSPs (Digital Signal Processors)—which consume heavy power and cause latency—and correcting signals using only Analog Equalizers. This reduces power consumption by tenfold and slashes latency from nanoseconds (ns) to picoseconds (ps).
> The Real Bottleneck in Optical Tech is the 'Light Source': While Co-Packaged Optics (CPO) is the correct long-term direction, the realistic winners for the next 2 to 3 years are Near-Packaged Optics (NPO) and 1.6T pluggable modules. The true bottlenecks in optical communication lie below the finished optical module layer: InP (Indium Phosphide) substrates, Continuous Wave (CW) laser sources, Photonics-SOI wafers (monopolized by Soitec), and SiPho foundries.
> Network Reliability and 'Link Flap': The "Link Flap" phenomenon, where an optical link momentarily blinks, disrupts the synchronization (all-reduce) of the entire AI cluster and leaves GPUs idling. In massive clusters, solutions that guarantee reliability rather than just bandwidth (such as Credo's Zero-Flap) become the ultimate bottleneck determining economic viability.

Let's unpack this a bit.
This is what management gave insight to on their latest earnings call:
> Q2: $180 million to $198 million
> Q3: A sequential revenue increase of 60% to 80% compared to Q2. So if Q2 lands at midpoint of $189 million,
เฮ้ย.. มันไปไกลถึงขนาดนี้แล้วเหรอ GPT-live ของ Open AI
จะเปิดมิติใหม่ของการเรียนภาษาผ่าน AI รึเปล่าวะนี่ เพราะมันมี real time correction ให้ได้แล้วฟังดู smooth มากอ่ะ เหมือนมีครูสอนภาษามาอยู่ข้างๆ แก้ไขไวยากรณ์และการเลือกใช้คำในโทนที่ไม่ judgemental
Memory+Compute+Networking is 80% of total CAPEX (China has no advantage here)
The rest 20% is power+cooling+shell
Assuming China is 50% cheaper compared to US
The max net savings is 10%
