Former employees of major AI companies urged greater oversight at a New York City Council hearing Monday, warning that developers may be advancing systems faster than they can control them.

Recently departed staff from Anthropic, OpenAI and Google DeepMind described what they saw as a reckless culture at the firms. Jacob Coxon, a former Anthropic engineer, told council members that AI could bring major benefits but argued that transparency and safeguards are needed to prevent a loss of control. He warned that, on the current course, such a loss could ultimately threaten humanity.

State and city governments are weighing AI regulation while Congress has not acted. President Donald Trump has dismissed fears about AI and signed an agreement late last month setting out voluntary steps for companies. AI firms have described their safety measures, though a coordinated slowdown in development faces obstacles.
