美制裁反助中國AI芯片崛起,Nvidia市佔大跌




英偉達在中國的挑戰:美國出口管制與國內人工智能競爭者的崛起

2022年,美國政府因國家安全顧慮,對向中國出口高性能人工智能晶片實施限制。英偉達(Nvidia)作為領先的人工智能晶片製造商,隨後開發了修改版晶片,如H20,以符合新規。然而,隨後的管制加嚴甚至使得這些合規晶片在中國也無法銷售,導致該公司遭受重大財務損失。

英偉達市場份額下降

英偉達首席執行官黃仁勳報告稱,該公司在中國的市場份額在四年內從95%下降至50%。他將這一下降歸因於美國的出口管制,他稱之為「失敗」,因為這反而刺激了中國國內人工智能的發展。中國公司,尤其是華為,趁著美國晶片的缺席,在人工智能硬體領域取得了顯著進展。

作為全球事務觀察員和獨立撰稿人,我認為美國對中國實施出口管制可能適得其反。中國國內人工智能行業的崛起,不僅挑戰了英偉達的市場地位,也推動了中國在人工智能領域的自主創新。華為等中國公司在人工智能硬體領域的進步,標誌著中國在這一領域的競爭力正在增強。

然而,這種趨勢也引發了人們對全球人工智能產業未來發展的擔憂。美國的出口管制可能導致全球人工智能產業的碎片化,進而影響全球創新和合作。如何在維護國家安全的前提下,促進全球人工智能產業的合作與創新,成為了一個迫切的課題。

此外,中國國內人工智能行業的崛起,也對全球人工智能產業的格局產生了深遠影響。中國在人工智能領域的自主創新,不僅推動了國內產業的發展,也為全球人工智能產業提供了新的機遇和挑戰。

總之,美國對中國實施出口管制,雖然出於國家安全顧慮,但可能適得其反,推動了中國國內人工智能行業的崛起。如何在維護國家安全的同時,促進全球人工智能產業的合作與創新,是一個需要深入探討的課題。

Create a hyper-realistic 8K close-up body portrait of a female model, using the uploaded photo as the exact facial reference. Maintain 100% accuracy of the facial features — do not alter or modify any aspect of the face. Render the skin texture, lighting, and overall composition with photo-realistic detail, ensuring lifelike color tones and natural depth of field. A man with his original hair is sitting casually on a white cube, smiling warmly at the camera. He is wearing a cream-colored cable-knit sweater, blue jeans, and brown loafers. His legs are crossed, with one hand resting on his knee.
The background reveals a cozy and festive living room. A large, beautifully decorated Christmas tree with numerous warm lights and gold ornaments stands prominently behind him. Several wrapped gift boxes are visible at the base of the tree. To his left, another smaller decorated Christmas tree and a wreath on the wall further enhance the holiday atmosphere. The lighting is soft and inviting, creating a warm and welcoming scene.

Do not alter the face, focusing on ultra-realistic details of the facial structure, eyes, eyebrows, nose, mouth, and expression. The final face must be realistic, not cartoon-like. She has long, voluminous hair.
1. Makeup:Maintain Original Face: We will preserve the structure of your face, eyes, eyebrows, nose, mouth, and expression as closely as possible to the original image to maintain naturalness and uniqueness, while adjusting the tone to be softer:

Eyes: Slightly reduce the sharpness of the Cat Eye eyeliner to a thin line close to the lash line for a softer look, while still maintaining eye definition.
Eyeshadow: Use natural tones like light brown, peach, or beige.
Eyebrows: Original shape, but brushed up to look softer and more natural.
Lips: Glossy, pink-tinted, nude-pink, or coral-toned lipstick/tint to make the lips look full and moisturized. Focus on a bright but not overly intense look.
2. Hairstyle:Natural Voluminous Long Hair: Her hair is long and flowing, but the styling will emphasize natural volume and movement. Soft, natural waves.
3. Outfit:

Attire: A white open-back bodysuit paired with distressed, faded blue denim shorts. There is a message "Kunika" on the shirt.
Shoes: Elegant, simple open-toe flat sandals.
Accessories: Styled freely and fittingly for each scene.
4. Poses & Sticker Elements:Poses: Various poses such as waving, jumping, walking playfully, reading a book, holding up a sign, cheering with both hands, stretching, or making a celebratory gesture, to create a cheerful and friendly atmosphere.Decoration: Include elements like small rainbows, sparkling stars, clear bubbles, hearts, balloons, or light-colored dots to decorate and enhance the fun of each sticker scene.Style: Thin black border around the sticker. Use a modern, rounded 'Itim' style font for the text.Text: Add short emotional phrases written in a cute, beautiful script near the sticker (no speech bubbles/text boxes):

"Hello"
"Love you"
"Submitting work"
"Great"
"Got it"
"Thanks!"
"Wait a sec"
"Ready to care"
"Fight"
"Let's do it"
"So cute"
"OK"
"Sweet dreams:
"Get well soon"
"555"
"You're welcome"
"HBD" 
"OMG" 
"Sorry"
"Got a headache" 
Guidelines: Do not include a text box. Ensure balanced composition with sufficient white space—not cluttered. Match the pose to the text.
Emphasis: Reiterate 'maintain 100% of the original face features from the provided image,' 'ultra-realistic facial detail,' and 'professional studio lighting on face (realistic face, not cartoon face).

Use Cantonese in the stickers.
