Sam Altman's $7 trillion chip dreams are way off the mark, says Nvidia CEO Jensen Huang

• Nvidia's CEO questioned Sam Altman's reported attempts to raise up to $7 trillion to boost GPU chip supply.
• Jensen Huang told the World Governments Summit in Dubai that the cost would be far lower. 
• He said building AI data centres globally would amount to just $2 trillion over the next five years.

Jensen Huang took an indirect jab at Sam Altman when he said $7 trillion can buy “apparently all the GPUs.”
