In a move that signals a paradigm shift in the regulation of the attention economy, California Governor Gavin Newsom has signed a comprehensive package of 13 laws designed to fundamentally alter how children interact with digital platforms. At the heart of this legislative blitz is AB 1709, a bill that takes aim at the core engineering of modern social media: the "addictive" features of infinite scroll and autoplay.
n
The legislation, signed in September 2026, marks the most aggressive attempt by any U.S. state to date to curb the psychological hold that technology companies maintain over younger demographics. By targeting the specific design choices that keep users tethered to their screens, California is moving beyond mere content moderation and into the realm of architectural regulation.

Main Facts: A New Era of Digital Guardrails
n
The legislative package signed by Governor Newsom is multi-faceted, but its primary impact lies in the restrictions placed on platforms frequented by users under the age of 16. The cornerstone of this effort, AB 1709, presents social media giants with a stark ultimatum: either disable specific "addictive" design features for minors or prevent them from accessing the platforms entirely.

Targeting the "Infinite" and the "Automatic"
n
The law specifically identifies two features as inherently predatory toward the developing brain:
n
- n
- Infinite Scroll: The design mechanism that allows users to browse through content without ever reaching an end-point or a "pagination" break.
- Autoplay: The function that automatically triggers the next video or piece of content without requiring a conscious "play" action from the user.

By removing these features, the law aims to reintroduce "stopping cues"—natural pauses that force a user to make a conscious decision about whether to continue their engagement.

AI and Privacy Protections
n
Beyond social media feeds, the package includes the nation’s strongest regulations on AI companion chatbots. These laws require age-limiting access to artificial intelligence that could potentially manipulate or exploit vulnerable minors. Furthermore, the 13-law suite strengthens privacy protections, ensuring that the data of children cannot be harvested to further refine the very algorithms that the state now deems addictive.

Chronology: From Innovation to Regret and Regulation
n
To understand the weight of these new laws, one must look back at the evolution of the features they now seek to ban. The journey from a "handy UI feature" to a "public health crisis" has spanned two decades.

2006: The Birth of the Infinite Scroll
n
The infinite scroll was created in 2006 by engineer Aza Raskin. At the time, it was hailed as a breakthrough in user experience, removing the friction of clicking "Next Page." However, Raskin has since become one of the feature’s most vocal critics. By 2018, he publicly expressed regret, telling the BBC that the industry had moved toward a model where "behind every screen on your phone, there are generally like literally a thousand engineers that have worked on this thing to try to make it maximally addicting."
n
2018–2024: The Rise of Short-Form Video
n
The arrival of TikTok and the subsequent pivot of Instagram (Reels) and YouTube (Shorts) combined infinite scroll with autoplay and highly sophisticated recommendation engines. This "perfect storm" of engagement engineering coincided with a sharp rise in reports of digital addiction and declining mental health among adolescents.

Early 2026: The European Precedent
n
In February 2026, the European Union utilized its Digital Services Act to demand that TikTok disable its addictive features. This international pressure provided the political momentum for California—often the "nation’s laboratory" for tech regulation—to draft its own specific prohibitions.
n
September 2026: The Newsom Signature
n
After months of heated debate in the State Capitol, Governor Newsom signed the package into law, positioning California as the first U.S. state to explicitly ban specific UI (User Interface) patterns based on their neurological impact.
n
Supporting Data: The Neurobiology of the "Dopamine Loop"
n
The impetus for these laws is grounded in a growing body of neuroscientific research. California’s legislators relied on data suggesting that the adolescent brain is uniquely susceptible to the "variable reward" systems utilized by social media.
n
Hijacking the Ancient Brain
n
According to reports from Stanford Medicine and other leading research institutions, the infinite scroll mimics the mechanics of a slot machine. Because the user does not know what the next piece of content will be, the brain releases a surge of dopamine in anticipation of a "reward" (an interesting video or a "like").
n
When this cycle is repeated thousands of times, the brain’s reward circuitry begins to require more stimulation just to feel "normal." For adults with fully developed executive function, resisting this loop is difficult; for children, whose prefrontal cortex—the area responsible for impulse control—is not fully formed until their mid-20s, it is often impossible.
n
The Problem of Passive Consumption
n
Psychologist Octavio Ortega Esteban has highlighted the specific danger of autoplay. "Autoplay skips over the moment where a person must actively choose whether or not to continue," he notes. This leads to "passive consumption," where the user is no longer an active participant in their own media choices but a passenger in an algorithmic stream.
The Displacement Effect
A critical concern cited by proponents of the law is "displacement." Every hour spent in a state of compulsive scrolling is an hour displaced from sleep, physical exercise, or face-to-face social interaction. In children, these activities are essential for healthy development. When scrolling becomes the default "displacement activity" for stress response, it establishes lifelong patterns of behavior that can lead to chronic anxiety and social isolation.
Official Responses: A Divided Digital Landscape
The enactment of these laws has sparked a fierce debate between those prioritizing child safety and those concerned with digital freedom and the "open internet."
The Governor’s Mandate
Governor Newsom’s office has framed the laws as a necessary defense against a predatory industry. "California is creating the strongest companion chatbot regulations in the nation and banning addictive features on social media platforms to protect kids from exploitation and abuse," the Governor’s office stated. The administration argues that the tech industry has failed to self-regulate, necessitating state intervention to protect the health of the next generation.
The Critique from Civil Liberties Groups
However, the legislation is not without its detractors. The Electronic Freedom Foundation (EFF) has voiced strong opposition, describing AB 1709 as "well-intentioned, but deeply flawed."
The EFF argues that by forcing platforms to either change their features or bar minors, the law will inadvertently cut young people off from essential information and supportive online communities. "This harms vulnerable youth and marginalized groups who often find safety in online spaces they cannot access offline," the EFF stated in a call for a veto. They worry that age verification requirements—necessary to enforce such a law—will compromise the anonymity and privacy of all users.
The Industry Perspective
While major tech companies have remained cautious in their public statements, industry trade groups have hinted at potential legal challenges. Their primary argument centers on the First Amendment, suggesting that the government cannot dictate how a private entity organizes and presents information.
Implications: The "California Effect" and the Future of the Web
The ramifications of California’s 13 new laws extend far beyond the state’s borders. Historically, when California passes stringent environmental or digital standards, the rest of the nation—and often the world—follows.
The "California Effect"
Because it is technically difficult and expensive for social media companies to maintain different versions of their platforms for different states, many may choose to implement these changes across the entire United States. If TikTok, Instagram, and YouTube are forced to remove infinite scroll for 16-year-olds in Los Angeles, they may find it more efficient to offer a "non-addictive" mode for all American minors, or even all users.
A Shift in Product Design
This legislation could signal the end of the "engagement-at-all-costs" era of product design. Engineers may now be tasked with creating "humane technology" that respects user autonomy rather than exploiting neurological vulnerabilities. We may see a return to "paged" content, "mindful" notifications, and transparent algorithms.
Potential for Legal Precedent
As these laws face inevitable challenges in court, they will test the legal boundaries of the state’s power to regulate software design. If the courts uphold California’s right to ban "addictive" features, it could open the door for similar regulations regarding other digital products, such as video games or online gambling.
Conclusion
California’s decision to ban infinite scroll and autoplay for minors is more than a regulatory hurdle for Big Tech; it is a declaration that the psychological well-being of children is a matter of public safety. By targeting the "ancient wiring" of the human brain and the "thousand engineers" who seek to exploit it, Governor Newsom and the California legislature have set a new standard for the digital age. Whether this leads to a healthier relationship with technology or a more fractured internet remains to be seen, but the days of unregulated, "infinite" digital consumption for children are likely coming to an end.
