One AI researcher who has been warning about the technology for over 20 years said to shut it all down.

Eliezer Yudkowsky said that the open letter calling for a pause on AI development doesn't go far enough.

Yudkowsky, who has been described as an "AI doomer," suggested an "indefinite and worldwide" ban.

The researcher has warned about the dangers of the technology since the early 2000s.

He said that we should "shut it all down," in an alarming op-ed published in a newspaper.

He wrote the article in response to an open letter from big names in the tech world, which called for a moratorium on AI development for 6 months.

The letter, signed by 1,125 people including Elon Musk and Apple's co-founder Steve Wozniak, requested a pause on training AI tech more powerful than OpenAI's recently launched GPT-4.

The article said that he refrained from signing the letter because it understated the seriousness of situation.

He explained that AI "does not care for us nor for sentient life in general," and we're far from instilling those kinds of principles in the tech at present.

Yudkowsky instead suggested a ban that is "indefinite and worldwide" with no exceptions for governments or militaries.
