Australia Kicks Kids Off Social Media + Is the A.I. Water Issue Fake? + Hard Fork Wrapped

December 12, 2025

Key Takeaways Copied to clipboard!

  • Australia has implemented the most aggressive social media ban in a democracy to date, barring children under 16 from 10 major platforms, which is seen as a potential first domino to reshape global internet usage. 
  • The narrative surrounding individual AI chatbot prompts causing significant water usage is largely considered a misreading of data, with the actual impact being negligible compared to overall daily water footprints or other industrial uses. 
  • The energy consumption of AI infrastructure, rather than its water usage, is identified as a more significant and immediate environmental concern, potentially leading to reliance on less environmentally friendly power generation sources. 
  • President Trump plans to use an executive order to sue states over AI laws and withhold federal funding from states that pass them, relying on a federal preemption argument that faces significant legal and political hurdles. 
  • China was named 'Other Country of the Year' for 2025 due to the impact of Chinese AI models like DeepSeek and the controversy surrounding the Trump administration's decision to allow NVIDIA to sell powerful H200 chips to China. 
  • The interview with Roblox CEO David Buzuki generated the most listener response of the year, highlighting public demand for accountability regarding platform safety, particularly after the CEO suggested introducing prediction markets to children's games.

  • Key Takeaway: Australia banned users under 16 from 10 major social platforms, requiring age estimation video selfies for verification.
  • Summary: The main topic is Australia’s new law banning children under 16 from using Facebook, Instagram, Threads, TikTok, Twitch, Snapchat, YouTube, X, Reddit, or Kik. Age verification must use methods like video selfies, invalidating simple birthday drop-down menus. The legislation was spurred by Jonathan Haidt’s book, The Anxious Generation.
Exclusions and YouTube Logged-Out Experience

(00:07:57)
  • Key Takeaway: Roblox and Discord were excluded from the initial ban, and YouTube’s logged-out experience may give it an advantage over Meta platforms.
  • Summary: Platforms like Roblox and Discord were excluded, with Roblox potentially added later after implementing new features. Critics suggest the government is picking winners and losers by omitting certain apps. YouTube’s ability to personalize feeds even when logged out is noted as a potential loophole compared to platforms like Instagram.
Teenage Reactions and Experiment Setup

(00:10:35)
  • Key Takeaway: None
  • Summary: Teenagers are preparing by creating backup accounts with older birthdates and downloading apps not covered by the ban, such as CoverStar and Yope. A notable, ancient response is the surge in teens exchanging unique phone codes to communicate directly. Australia plans to fund academic researchers to study the long-term effects of this social media removal experiment.
Predicting Effects of Social Media Ban

(00:13:03)
  • Key Takeaway: The Australian ban represents a crucial natural experiment on the mental health effects of removing social media from youth.
  • Summary: The hosts anticipate that while short-term effects might be minimal, long-term outcomes over five to ten years could show steep differences compared to previous generations. The ban is seen as a necessary public health restriction, similar to alcohol or tobacco controls, despite concerns for creators or marginalized youth who rely on these platforms. Other nations, including Denmark, Norway, and Malaysia, are already pursuing similar legislation.
AI Water Use Narrative Debunked

(00:22:55)
  • Key Takeaway: Individual AI chatbot prompts use minuscule amounts of water (around 0.26 to 2 milliliters), making the ‘bottle of water’ claim false.
  • Summary: Blogger Andy Maisley argues that the focus on AI water usage is a distraction from more pressing environmental issues like energy infrastructure. The average American’s daily water footprint is about 1,600 liters, meaning a user would need to send roughly 8,000 median prompts to increase their footprint by 1%. Maisley suggests that AI’s impact on water is comparable to a 1% increase in irrigated corn usage by 2030.
AI Energy vs. Water Concerns

(00:37:09)
  • Key Takeaway: The increase in electricity demand from AI data centers (projected 0.5% to 5% of the US grid by 2030) is an order of magnitude greater concern than water usage.
  • Summary: The primary environmental worry regarding AI infrastructure is the strain on the electrical grid, which could lead to continued reliance on fossil fuels like coal or fracking. Water usage by data centers, while large industrially (estimated at eight times a small town’s usage in 2023), is expected to be absorbed by existing systems. Data centers can also provide positive local impacts, such as increased tax revenue and utility upgrades for aging infrastructure.
Data Misdirection and AI Accelerationism

(00:45:16)
  • Key Takeaway: Both AI critics and proponents use selective data—like focusing on inference vs. training costs—to support their respective narratives.
  • Summary: Hank Green’s observation that both sides use bad data is acknowledged; critics focus on training costs while companies highlight low per-prompt inference costs. Maisley worries that debunking the water issue is being co-opted by AI accelerationists to dismiss all environmental concerns, which he opposes as an environmentalist. He advocates for focusing on larger systemic issues, like the green energy transition, over individual user footprints.

Trump Executive Order on AI

(00:57:38)
  • Key Takeaway: Trump plans to use executive action to sue states over AI laws, citing interstate commerce infringement.
  • Summary: President Trump announced plans to sign an executive order to curb state AI laws, directing the U.S. attorney to sue states if these laws infringe on interstate commerce. The plan also involves telling federal regulators to withhold broadband and other funding from states passing such AI laws. This strategy is based on ‘federal preemption,’ an idea that previously failed in the Senate 99 to 1.
Hard Fork Wrapped: Other Country

(01:00:03)
  • Key Takeaway: China is named Hard Fork’s ‘Other Country of the Year’ for 2025 due to AI development.
  • Summary: China earned the title due to the initial freak-out over DeepSeek’s R1 model suggesting it could overtake the US in AI development, which influenced US regulation debates. Reporting indicates that the number of free, open-source models used by American companies that are Chinese-made has been rising significantly. This recognition is also tied to the recent decision allowing NVIDIA to sell powerful H200 chips to China.
NVIDIA Chip Sales to China

(01:02:32)
  • Key Takeaway: The Trump administration approved NVIDIA selling H200 chips to China, taking a 25% cut of sales.
  • Summary: NVIDIA CEO Jensen Huang has lobbied to sell advanced H200 chips to China, despite national security concerns from US officials worried about eroding the US lead in frontier models. The administration approved the sale, taking a 25% cut, though it is unclear if the Chinese government will permit domestic use given their domestic chip development efforts. Evidence suggests Chinese companies like DeepSeek are already smuggling top-tier Blackwell chips into the country.

  • Summary: The interview with Roblox CEO David Buzuki generated the most listener response, driven by journalists asking direct questions about child safety failures on the platform. Listeners expressed frustration with platform executives who seem unprepared for tough questions, possibly due to spending too much time on friendly creator podcasts. The most surprising moment for the hosts was the CEO’s suggestion to consider adding prediction markets (gambling) to children’s games.
