For example, it cannot completely imitate human emotions and creativity, nor can it replace human judgment and thinking ability. 4. Environmental pollution and waste of resources: The development of science and technology has also brought problems of environmental pollution and waste of resources. Problems such as electronic waste and waste water are becoming more and more common, which requires us to explore a more sustainable development model of science and technology. 5.
