A handful of tech companies are jeopardising humanity’s future through unrestrained AI development and must stop their “race to the bottom”, according to the scientist behind an influential letter calling for a pause in building powerful systems. Max Tegmark, an AI researcher, warns that unrestrained AI development by tech companies poses a threat to humanity and calls for regulation. Tegmark organized an open letter signed by industry figures, including Elon Musk, calling for a pause in giant AI experiments. AI experts suggest governments should have the authority to halt the development of exceptionally powerful AI models. Concerns arise about unchecked artificial general intelligence development, and leading tech companies, including Amazon, Microsoft, Alphabet's Google, Meta (Facebook's parent company), are making significant AI investments. AI investment is booming, with potential to transform the global economy, while new AI startups receive substantial funding.
