- 35-year-old Daniel Harper's manifesto cited AI extinction in sam-altman-attack.
- Fear & Greed Index drops to 21 as Bitcoin surges 5.1%.
- OpenAI boosts security 40% after threats doubled post-GPT-5.
On April 14, 2026, 35-year-old Daniel Harper launched a sam-altman-attack on OpenAI CEO Sam Altman's Pacific Heights mansion at 4:17 a.m. Driven by AI extinction fears, he vaulted the fence, smashed a window with a knife, and shouted warnings. Guards tackled him inside. No injuries reported.
Police arrested Harper blocks away. Altman, home alone, stayed unharmed. Authorities seized his 18-page manifesto blasting OpenAI's superintelligence push.
Sam Altman Attack: Harper's Slide to Extremism
Harper coded AI tools at a Silicon Valley startup until 2024. "He obsessed over doomer forums like LessWrong," former colleague Raj Patel, a data scientist there, recalled. Harper quit in 2025, posting online: "OpenAI builds the apocalypse."
He cut off friends and sold his apartment for $850,000 USD last month. He converted proceeds to 2.3 BTC, now worth $171,000 USD per CoinMarketCap.
Sam Altman warned Congress about AI risks in 2023. Harper twisted those words into his manifesto.
Foggy Dawn Breach at Altman's Estate
Fog shrouded the luxury estate. Harper jammed security drones with a homemade jammer. He burst into the living room, pepper spray ready, toppling chairs and tables.
Guards pinned him fast. Police searched his van, uncovering OpenAI papers and alignment failure docs. FBI Special Agent Maria Lopez labeled it "classic AI extremism." Prosecutors filed federal attempted murder charges.
"He charged like a man with nothing left," SFPD Captain Elena Vasquez, who commanded the scene, said.
Threats Mount Against Altman's OpenAI Empire
Sam Altman, 41, steers OpenAI's $6.6 billion valuation with Microsoft backing. GPT-5's 2025 launch doubled threats against him, internal logs show.
Altman ramps up safety research funding. Bodyguards trail him nonstop. OpenAI spiked its security budget 40% this quarter, a spokesperson confirmed.
Yoshua Bengio, AI pioneer and Turing Award winner, warned: "Unchecked debates spark violence."
Crypto Surge Amid AI Panic Trades
Markets reeled. Alternative.me's Fear & Greed Index crashed to 21.
Bitcoin jumped 5.1% to $74,383 USD (CoinMarketCap). Ethereum rose 8.0% to $2,368.61 USD. Volume spiked 25%.
XRP climbed 3.5% to $1.37 USD. BNB gained 3.6% to $614.63 USD. "Traders view BTC as hedge against AI turmoil," crypto analyst Mia Chen of Galaxy Digital said.
Human Cost of Silicon Valley AI Wars
Harper embodies the toll. SFPD Captain Vasquez reported 15 threats in Silicon Valley since 2025. Center for AI Safety's Dan Hendrycks counted 22 incidents last year.
OpenAI paused non-essential travel. Altman emailed staff: "We press on for humanity's future."
Accelerationists and PauseAI activists denounced the sam-altman-attack. Safety investments reached $1.2 billion USD in Q1 2026. Regulators eye tighter oversight to curb violence.
