Hundreds marched through King's Cross chanting 'Stop the slop.' The AI backlash is getting real.

I Went to London’s Biggest Anti-AI Protest — Here’s What I Learned

On February 28, a couple hundred anti-AI protesters marched through King’s Cross — London’s AI hub, home to OpenAI, Meta, and Google DeepMind UK offices. They chanted “Pull the plug!” and “Stop the slop!” Organizers called it the largest protest of its kind yet.

And here’s the thing: they had a point.

What They’re Worried About

The concerns ran the gamut from the practical to the existential:

  • AI slop: Researchers complained that AI-generated content is making it impossible to find reliable academic sources
  • Job displacement: An older man with a sandwich board read “AI? Over my dead body” — worried about unemployment
  • Killer robots: Signs referenced Demis Hassabis (DeepMind CEO) with “Demis the Menace”
  • Human extinction: Some genuinely believe AI could end humanity

One woman wore a billboard on her head with “WHO WILL BE WHOSE TOOL?” — with the Os cut out as eye holes. Creative.

Why This Matters Now

This wasn’t always mainstream. The first anti-AI protest I covered was in May 2023 — just 2-3 people heckling Sam Altman outside a London lecture hall. By mid-2025, a few dozen showed up outside Google DeepMind’s office. Now we’re talking hundreds.

Joseph Miller, director of Pause AI’s UK branch and a PhD student at Oxford, told the reporter he’s “on an exponential path, matching the progress of AI itself.”

The Irony

The protest happened the same week the Pentagon tried to force Anthropic to remove Claude’s safety checks so it could use the AI for “any legal military purpose.” Anthropic refused — “cannot in good conscience” — and now the Trump administration is blacklisting Claude from government entirely.

The protesters want AI paused. The government wants it weaponized. Both sides agree something fundamental is at stake.

What This Means for You

Whether you think the protesters are paranoid or prescient, the movement is growing. A few takeaways:

  1. AI fatigue is real: Not everyone is bullish on AI. Public skepticism is becoming organized.
  2. Regulatory pressure will increase: Expect more protests, more legislation, more corporate pushback.
  3. The ‘slop’ problem isn’t going away: If you work in content, research, or media, AI contamination is your problem now.
  4. Tech companies are listening (sort of): Pause AI’s organizers say they can’t pressure companies directly — but they can slow the race by making it politically costly.

The Bottom Line

Love it or hate it, the AI backlash just got louder. The question isn’t whether there’s a counter-movement — it’s how big it gets.

If hundreds showed up in London last week, what’s the crowd size look like in six months?
