All seven Anthropic cofounders are donating 80% of their combined $3.7 billion each now, warning that AI-driven wealth concentration will “break society.” They see this pledge as insurance, urge progressive taxation on AI gains, and note employees are matching share donations to prepare for massive economic upheaval.

• Anthropic's seven cofounders are pledging 80% of their combined $3.7 billion now, not after death, as Anthropic's valuation rocketed from $4.1B to ~$350B in about two years
• Dario Amodei's essay predicts half of entry-level white-collar jobs could vanish within five years and frames philanthropy as insurance against social breakdown ("pitchforks outside your house")
• Amodei argues voluntary giving can't scale to match AI-driven wealth concentration, so he's pushing for mandatory progressive taxation on AI-generated wealth
• Anthropic is considering keeping employees on payroll even after their economic value fades, effectively a corporate UBI
