There will be a lot of changes in the next 30 years. With the continuous development of technology, our lives will become more convenient and efficient. At the same time, we will also face many challenges, such as climate change, resource shortages and other issues.

Firstly, in technology, artificial intelligence will become the dominant technology in the future. With the continuous improvement of technologies such as machine learning and natural language processing, artificial intelligence will become smarter and better able to adapt to various application scenarios. In addition, blockchain technology will also become an important technology in the future, which can provide more secure and transparent transaction and data management methods.

Secondly, we will face greater challenges in environmental protection. With the aggravation of climate change and resource shortages, we need to take more active measures to protect the environment. This includes reducing carbon emissions, improving energy efficiency, promoting renewable energy, etc.

Finally, in terms of population and society, we will face aging and population decline. This requires us to take appropriate measures to deal with, such as encouraging birth, developing the elderly industry, promoting social security, etc.

Overall, the next 30 years will be an era full of challenges and opportunities. We need to take active measures to respond to these challenges and use these opportunities to create a better future.
