1 . Artificial intelligence carries the promise of making industry more efficient and our lives easier. With that promise, however, also comes the fear of job replacement, increased income inequality, and overall dissatisfaction. According to the quarterly CNBC/Survey Monkey Workplace Happiness survey last year, 37% of workers between the ages of 18 and 24 were worried about AI stealing their jobs.

But a recent study from two researchers working for the Stanford Institute for Human-Centered Artificial Intelligence(HAI) challenged this public perception(看法) of AI’s impact on social welfare. The study found a relationship between AI-related jobs and increases in economic growth, which in return improved the well-being of the society.

Demand for Al-related jobs has been growing constantly in recent years, but this growth has been widely variable between cities and industry. Arizona State University assistant professor Christos Makridis and Saurabh Mishra, HAI AI Index manager and researcher, wanted to understand the effects of AI on society independent of these variables.

For this, they examined the number of AI-related job listings by cities in the U. S. , using Stanford HAI’s AI Index, an open source project that tracks and visualizes data on AI. They found that, between 2014 and 2018, cities with greater increases in AI-related job postings exhibited greater economic growth. This relationship was dependent on a city’s ability to take advantage of its natural capabilities in industry and education to create AI-based employment opportunities. This meant that only cities with certain infrastructure, such as high-tech services and more educated workers, benefited from this growth.

Next, the researchers studied how this growth was translated into well-being at a macro(宏观) level using data from Gallup’s U. S. Daily Poll, which surveys 1, 000 different people each day on five parts of well-being: physical, social, career, community and financial. They found that AI-related job growth was positively associated with improved state of being, especially for physical, social and financial parts.

This was a surprising finding given the public’s concern over AI’s potentially unfavorable effects on quality of life and overall happiness.
