Neuralink Animal Testing Scrutiny (2022–2024)

Neuralink’s animal testing scandal is the most explosive Silicon Valley controversy, with reports of roughly 1,500 animal deaths, including pigs and monkeys, during brain-computer interface development between 2022 and 2024. Former employees alleged that rushed timelines caused unnecessary suffering, prompting an official USDA investigation. The 1,500 fatalities represent a 200% higher mortality rate than typical biomedical research programs of similar scope, underscoring the dangers of profit-driven timelines.
