The 996 Work Culture, Marked by Up to 12-Hour Daily Shifts for Six Days a Week, Begins to Solidify in Silicon Valley Amid the Race for Advancements in Artificial Intelligence, Increasing Pressure on Technical Teams and Exposing Human Limits Reported by Industry Researchers

The rise of the work culture known as “996” in Silicon Valley occurs in a context of intense competition among artificial intelligence companies, leading researchers to report extended hours, constant pressure for deliveries, and direct impacts on health, personal life, and work sustainability in the sector.

996 Work Culture Gains Ground in AI Companies in California

The work culture 996 defines six-day workweeks, from 9 AM to 9 PM, a model established in China that is beginning to appear in the tech landscape of San Francisco. Although Silicon Valley is already associated with intense routines, some companies have started adopting stricter formats, close to the 996 standard.

According to reports, this movement is linked to the so-called “AI war,” characterized by rapidly succeeding models of artificial intelligence to surpass competitors. In startups, the pressure to grow and stand out increases the demands on technical teams and researchers.

Competitive Pressure Shapes the Work Culture in the Tech Sector

During a participation in a podcast hosted by Lex Fridman, the founder of an AI research lab Sebastian Raschka stated that the environment observed in Silicon Valley does not yet fully replicate the Chinese model but shows clear signs of convergence.

He highlighted that the combination of passion and competition fuels this work culture. Raschka reported that, in his academic experience in AI, he was not forced into excessive hours, but chose them due to the demands of the field, stating that “it is really difficult because you have to constantly deliver.”

Leading Companies Reflect the Same Pattern of Extreme Dedication

The senior scientist at the Allen Institute for AI Nathan Lambert stated that this behavior is already visible in widely recognized companies in San Francisco and the AI industry. According to him, environments like those at OpenAI and Anthropic operate under high pressure, with employees voluntarily adhering to the intense routine.

Lambert noted that programmers, in particular, accept this model because they wish to be directly involved in technological advancement. The mentioned companies did not respond to requests for comment from media outlets.

Human Costs and Limits of Prolonged Work Culture

Despite the engagement, Lambert warned that this work culture imposes a “human cost,” including less time with family, a limited view of the external world, and, in some cases, health issues. He stated that this pace is not sustainable indefinitely and that signs of burnout are already evident.

Raschka reported personal physical consequences, such as back and neck pain, associated with the lack of adequate breaks during long working hours.

For young programmers, this environment can become almost inevitable if they wish to stand out in the field.

According to Lambert, being physically in Silicon Valley increases the chances of impacting AI but involves clear trade-offs. He summarized that the opportunity exists, but with limits, emphasizing that the current work culture demands tough choices and sometimes exacts a high toll on the professional.

Human Costs and Limits of Prolonged Work Culture

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

A robot named Walter does the work of five bricklayers per hour and can save the construction industry, where the average age of professionals is 46 years and almost no one wants to learn the trade anymore, in the United Kingdom.

Spain installs two giant pipelines 2.2 km off the coast to draw water from the Mediterranean and supply a megafacility capable of producing 200 million liters of drinking water per day.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

While common buildings in São Paulo or Berlin occupy the ground for years, in China a horizontal skyscraper the size of the Empire State Building was erected in record time, transforming the city and inspiring new urban solutions.

One of the most challenging bridges in the world is assembled in Malaysia with helicopters, prefabricated parts, and a single pillar to support the curved deck over the mountain.

While conventional religious buildings prioritize height and ornaments, a mosque in Istanbul occupies 1,300 square meters of land but remains almost invisible, gaining international recognition for its innovative design.

While historic squares in Europe preserve only ruins, in Seville a giant wooden structure with six 150-meter mushrooms creates a market, viewpoint, and panoramic walkways over archaeological remains.

It looks like an upside-down subway, but it’s actually a train that has been traveling 13 km suspended over rivers and streets in Germany for 125 years, transporting more than 80,000 passengers a day and attracting tourists from all over the world.
