According to a report by global consultancy McKinsey, generative artificial intelligence could add between $2.6 trillion and $4.4 trillion to the global economy annually in the coming years. The report predicts that generative AI will automate high-paying knowledge-based jobs on a large scale, such as sales and marketing. AI automation is likely to first become popular in wealthy countries like the United States, while adoption may be slower in countries like India, potentially widening the income gap in employment across nations. It is important to approach the impact of AI technology on the job market with caution and to pay attention to risks such as algorithmic bias and data security, with appropriate regulation of the industry's development.
