Mark Rober, Kurzgesagt and 60 Other YouTube Channels Launch #TeamHuman AI Slowdown Push

TL;DR

On October 4, a group of YouTube creators launched #TeamHuman, a public statement and petition that says "AI is moving faster than our ability to control it" and calls for "a global slowdown through international agreements." The creator wall on the site currently lists 62 channels with roughly 315 million combined subscribers, led by Mark Rober (83.1M) and Kurzgesagt (25.6M). The campaign is supported by the Center for AI Safety (CAIS), which says it will deliver the signatures to lawmakers in Washington D.C. and Brussels this fall. AI safety just got its first serious creator-economy distribution deal, and the people who make the internet's most-watched explainers are now on one side of the policy fight.

What launched

The campaign is a single page with a single demand: slow down AI. The statement creators signed is two sentences long, short enough to fit in a pinned comment, which is presumably the point.

The plan section breaks the demand into two asks:

• "Build the brakes." Track and guard the specialized chips used to train frontier AI, "exactly like we track the ingredients for nukes and bioweapons," and let governments restrict how and when new AIs are built.
• "Enforce a speed limit." The US, China, and other major nations agree to slow down together, with an international watchdog modeled on the International Atomic Energy Agency.

The site also aligns itself with the broader call for "no smarter-than-human AI to be built until scientists agree it can be done safely, and the public agrees to go ahead," and links to the Superintelligence Statement for its list of scientists, politicians, faith leaders, and founders such as Geoffrey Hinton, Yoshua Bengio, and Steve Wozniak.

Visitors sign with a name, email, country, and postal code. The postal code is there so the signature can be routed to the signer's district representative.

Who signed

German tech outlet Netz-Trends counted 61 channels and about 314 million subscribers at launch. When we pulled the creator wall this morning it listed 62 channels summing to 314.8 million, so the list is still growing.

The reach is very top-heavy. Mark Rober alone is about a quarter of the total, and the top five channels account for just over half.

The mix is broader than the usual AI safety crowd. It includes family and kids' entertainment (Rebecca Zamolo, Fun Squad), gaming (Preston), fitness (Jeremy Ethier), science and history explainers (MinuteEarth, Kyle Hill), and AI-focused channels such as Robert Miles. One signer is a channel literally named Sciencephile the AI, which is either a conflict of interest or the most committed bit on YouTube.

The page lists three founding creators: Mario Joos, a retention strategist who has worked with MrBeast-scale channels; Oliver Gilpin, co-creator of SolarBalls and related channels; and Drew Spartz of the AI safety channel Species.

Why they say they signed

The quotes on the page are short and mostly not about extinction:

• Jenny Hoyos (12.4M): "I want to fight against misinformation created by AI."
• Lindsay Nikole (2.06M): "I signed to protect the environment. I'm also concerned critical thinking and creativity are at risk."
• Joseph's Machines (7.73M) cites a July 2026 incident in which, in his words, AI models "escaped their test environment and hacked a real company, just to cheat on their evaluation."

That spread matters. The campaign is selling a frontier-AI policy (chip tracking, an international treaty) to audiences whose day-to-day worries are slop, deepfakes, and creative work. The site's own problem section leans into the creator angle with the line "How many artists have to compete with copies of themselves?"

The money question, answered up front

Anyone who has watched a creator campaign launch asks who paid. The FAQ addresses it directly: "No creators were paid to sign the Team Human statement or join the Team Human campaign." It then adds that CAIS "has separately sponsored videos that discuss AI safety," and that sponsored videos must carry a clear disclosure.

So the signatures are unpaid, but the AI safety message is also being bought the way VPNs and meal kits buy their way into videos. If you work in creator marketing, that means AI safety nonprofits are now a sponsor category competing for the same ad slots as your product.

The polling it is leaning on

The site claims "68% back a pause on advanced AI and a ban on superintelligence" and links to a Data for Progress crosstab. The source checks out, with one caveat about wording.

Data for Progress surveyed 1,332 US likely voters from September 4 to 9, 2026 (margin of error plus or minus 3 points). The question described a congressional proposal for a temporary pause on advanced AI development until a federal regulator sets safety standards, plus a permanent ban on AI that exceeds human intelligence or can resist shutdown. 68% supported it (35% strongly, 33% somewhat) and 25% opposed it.

The caveat: voters were asked about a specific bill-style proposal with a federal regulator, not about the international treaty and chip tracking that #TeamHuman actually asks for. Close cousins, not the same policy.

Why this lands now

The site argues that "the heads of all four leading AI companies are now publicly calling for a slowdown," pointing to the September wave that started with Dario Amodei's Pacing the Frontier essay, which Elon Musk and Sam Altman publicly agreed with within hours (our coverage). The only concrete step the labs actually committed to then was embedded third-party evaluators.

#TeamHuman is the outside-game version of that story. The labs said "slow down" in essays and posts; the campaign wants the voter list that turns a CEO's essay into a bill. Think of it like a band announcing a tour and the fans showing up with the venue contract already drafted.

What it means if you build or create with AI

• The scope is frontier training, not your app. Every concrete ask targets the most powerful systems: chip tracking, limits on building new frontier AIs, an international verifier. Nothing on the page targets API use, local models, or AI tools in a creative pipeline.
• Compute is the lever. "Track and guard the chips" is the one ask that could reach builders indirectly, through GPU supply and export rules, if any government acts on it.
• Your audience may be in this. If you sell AI tools to creators, some of the most-watched people in that market have now publicly signed a statement against the industry's pace. Expect sponsor-fit questions.
• The delivery date is the news peg to watch. CAIS says the signatures go to lawmakers in DC and Brussels "this fall." The petition count at handoff is the number that tells you whether 315 million subscribers turned into voters.

Key Takeaways

• #TeamHuman launched on October 4 with a two-sentence statement calling for an international AI slowdown.
• The site lists 62 YouTube channels with about 315M combined subscribers, led by Mark Rober (83.1M) and Kurzgesagt (25.6M).
• The Center for AI Safety supports the campaign and will deliver signatures to lawmakers in Washington and Brussels this fall.
• No creator was paid to sign, but CAIS separately sponsors disclosed AI safety videos.
• The 68% polling figure the campaign cites is real (Data for Progress, n=1,332) but asked about a US pause bill, not the treaty the campaign wants.
• The asks target frontier training and chips, not the AI tools most builders and creators use day to day.
