Increasingly powerful artificial intelligence tools won't inevitably translate to faster economic growth, OpenAI Chief Economist Ronnie Chatterji says at the ECB Forum on central banking in Sintra. Without innovation, investment and adaptation at all levels of the economy, higher output is likely to face bottlenecks, he says. Chatterji gives the example of the pharmaceutical industry, which may be able to speed up drug discovery with the use of AI, but will still face manufacturing, infrastructure, testing and regulatory hurdles. Where possible, policymakers and organizations should work to ease these bottlenecks, he says. "We could have amazing intelligence, super-capable intelligence. I would argue even today it's super capable, but... a big piece of GDP growth comes through accelerating innovation," Chatterji says. (don.forbes@wsj.com)
