Fears about AI are not new.

But these fears are getting more attention now.

People worry about AI systems that act badly.

Some top AI bosses want to slow down.

They want countries to work together.

They want to protect people from the worst cases.

Other tech leaders disagree.

They say their companies can keep AI safe alone.

Dario Amodei is the CEO of Anthropic.

He has the most detailed plan to slow down.

He said top labs should let outside experts watch them.

These experts would have long-term access.

They would get offices, badges and laptops.

Anthropic and OpenAI both agreed to this.

Amodei also wants government rules.

He wants frontier AI companies to work together.

He wants democratic and authoritarian governments to work together too.

He said this is hard.

He named China as a hard case.

But he said, "we owe it to humanity to try."

Sam Altman is the CEO of OpenAI.

He supports a slower pace.

He supports more teamwork in the industry.

OpenAI wants safety rules from the national government.

It also backs state laws.

Chris Lehane is its chief global affairs officer.

He said the company will push for global ways to measure AI power.

It will push for global ways to manage risk.

This may slow down AI models.

Altman said a slower pace is not a stop.

He said, "no amount of American competitive pressure should justify recklessness."

Mark Zuckerberg is the CEO of Meta.

He pushed back.

He said each company should keep its own tech safe.

Jensen Huang is the CEO of Nvidia.

He also criticized the slowdown calls.

He said the market is enough.

He said no new laws are needed.

Elon Musk backed Amodei.

He wrote, "Dario is right."

He said rivals should test each other's models.

Demis Hassabis is from Google DeepMind.

He agreed with Amodei's direction.

He proposed a group to set AI standards.

The industry would pay for it.

Satya Nadella is from Microsoft.

He said AI must help people.

It must stay under human control.

But he warned that a few groups cannot control it all.

Mustafa Suleyman is the CEO of Microsoft AI.

He said he worries about one thing.

He worries that treating models like people makes safety risks worse.
