Silicon Valley is happy with the White House's hands-off approach to AI rules.

At a busy Tech Week in San Francisco, founders and investors said this would help companies that build AI defense and security systems.

The event was part of a series organized by Andreessen Horowitz.

Its head advises Trump on science and technology.

President Donald Trump signed a 308-word voluntary safety agreement with major AI labs last month.

It says advanced labs should follow safety rules and check their own progress.

But the administration has not explained how it will stop what OpenAI CEO Sam Altman called "bad things."

Trump ended a Biden-era order on AI risks.

He also canceled rules that required developers to share safety test results.

Some experts doubt that self-policing will work.

David Robinson recently left OpenAI's safety team.

He said the pact gives companies too much freedom and cannot replace hard law.

Sarah Myers West of the nonprofit AI Now said self-regulation has always failed.

Three OpenAI researchers said they were fired after posting that fear and unclear rules slow safety work.

Trump has tied his political success to the AI industry's success.

He called free development key to beating China.

He warned voters not to "kill the Golden Goose."

The FTC has opened an investigation into OpenAI, Anthropic and others.

Critics, including former Treasury official Graham Steele, ask whether companies should hold this much power.
