(Intel CEO Lip-Bu Tan holds a wafer of CPU tiles for the Intel Core Ultra series 3)

Meanwhile, the recent progress of Intel’s wafer foundry business has received attention. Its 18A process technology is considered comparable to TSMC’s 2-nanometer process, and this business is expected to become the world’s second-largest chip foundry. The US government invested $8.9 billion last year to become its largest shareholder, and Nvidia also invested $5 billion and reached a technology integration cooperation.

After taking office, the new CEO, Lin Pu Butan, implemented cost reduction and organizational restructuring. Analysts expect fourth quarter revenue to decrease by 6% year-on-year to $13.4 billion, but data center and AI sales may surge by 29% to $4.4 billion. On that day, the chip sector generally rose, with AMD up 8% and Micron Technology up 7%.

Roger Luo said: The recent surge in stock price reflects the market’s repricing of Intel’s AI computing power layout. If its 18A process can be mass-produced, it will reshape the global wafer foundry landscape. But it is necessary to pay attention to whether the growth of data center business can continue to offset the decline of traditional business, as well as the actual progress of customer expansion in OEM business.

If the rumors come true, this will be another sign of the intensifying competition in the artificial intelligence hardware market. Previously, Chris Rehan, Global Affairs Director of OpenAI, stated at the Davos Forum on Monday that the company expects to release its highly anticipated first artificial intelligence hardware device in the second half of this year. Another report suggests that the device may be an earbud style earphone.

The report describes Apple devices as “thin and flat circular disc-shaped devices with aluminum and glass shells”, and engineers hope to control their size to be similar to AirTag, “only slightly thicker”. It is reported that the badge will be equipped with two cameras (standard lens and wide-angle lens respectively) for taking photos and videos, as well as physical buttons and speakers, and a charging contact similar to FitBit on the back.

According to reports, Apple may be trying to accelerate the development progress of the product to cope with competition from OpenAI. The smart badge is expected to be released as early as 2027, with an initial production capacity of up to 20 million units. TechCrunch has contacted Apple for more information regarding this matter.

However, it remains to be seen whether such artificial intelligence devices can gain market recognition. The startup company Humane AI, previously founded by two former Apple employees, has launched a similar artificial intelligence badge, which also has a built-in microphone and camera. But the product received a lukewarm response after its launch, and the company was forced to cease operations within two years of its release and sell its assets to HP.

Roger Luo said:This news indicates that the competitive focus of AI is shifting from the cloud to hardware carriers. Apple’s advantage lies in its integrated ecosystem of software and hardware, but this “AI pin” must address fundamental challenges such as scene definition, privacy anxiety, and battery life in order to truly open up a new category of wearable intelligence.

According to its official announcement, all mobile applications will be taken down before February 16, 2026, while desktop version services will not be affected. MacPaw explained in a statement that the main reason for the shutdown was due to Apple’s “continuously evolving and overly complex” charging mechanism to comply with DMA implementation, especially the controversial “core technology fee” – which stipulates that developers must pay 0.5 euros per installation after the first installation exceeds 1 million times per year in the past 12 months.

Although Apple revised its fee structure last year to avoid penalties for violations, its regulatory system has become more complex. Setapp pointed out that the constantly changing business environment makes it difficult for its existing model to operate sustainably, and “commercial feasibility cannot be achieved under current conditions”. As an early platform to enter the EU alternative store market, Setapp’s exit reflects the common challenges faced by third-party app stores under Apple’s current framework.

At present, there are still other alternative stores operating in the EU market, including the Epic Games Store and the open-source platform AltStore. This shutdown event may trigger a new round of discussions on the actual implementation effectiveness of DMA and the compliance strategies of technology giants.

Roger Luo said:The exit of Setapp is not an isolated case. The new barriers built by giants through technical compliance may still stifle the innovation and competitive vitality expected by the market.

(Boron Carbide Ceramic)

Boron carbide (B FOUR C) stands as one of the most interesting and technologically important ceramic materials as a result of its distinct combination of severe solidity, reduced density, and exceptional neutron absorption capacity.

Chemically, it is a non-stoichiometric substance primarily made up of boron and carbon atoms, with an idyllic formula of B FOUR C, though its actual make-up can vary from B FOUR C to B ₁₀. FIVE C, reflecting a vast homogeneity array governed by the replacement mechanisms within its facility crystal latticework.

The crystal framework of boron carbide belongs to the rhombohedral system (room team R3̄m), identified by a three-dimensional network of 12-atom icosahedra– clusters of boron atoms– linked by straight C-B-C or C-C chains along the trigonal axis.

These icosahedra, each including 11 boron atoms and 1 carbon atom (B ₁₁ C), are covalently bonded through extremely solid B– B, B– C, and C– C bonds, contributing to its impressive mechanical rigidity and thermal stability.

The visibility of these polyhedral devices and interstitial chains introduces structural anisotropy and inherent flaws, which affect both the mechanical behavior and electronic buildings of the material.

Unlike simpler ceramics such as alumina or silicon carbide, boron carbide’s atomic style allows for considerable configurational adaptability, making it possible for defect development and fee circulation that impact its performance under tension and irradiation.
