The World Bank estimates that up to 77% of jobs in China could be made redundant by machines in the long term. Investing in robots will become more attractive for manufacturers. The Chinese government also pledges to make China a “world factory” of robots. But real changes are much slower. Reports say that large numbers of workers are still used on production lines doing repetitive tasks such as scrubbing speaker systems with toothbrushes. Despite the fact that China’s labor costs are six times higher than 10 years ago, workers are often still cheaper than robots in short term.
