The future development trend of modern sculpture can be discussed from many aspects:

1. **Technology integration**: With the advancement of science and technology, especially the development of technologies such as 3D printing, virtual reality (VR) and augmented reality (AR), sculpture art will be increasingly combined with these new technologies. Artists can use these tools to create more complex and interactive works.

2. **Sustainability and environmental protection**: As global attention to environmental issues increases, sculpture artists may pay more attention to the use of renewable materials and environmentally friendly technologies to create works that reflect ecological awareness. This trend is not only reflected in the choice of materials, but also in the theme and concept of the work.

3. **Social participation and public art**: Future sculptures may pay more attention to interaction with the community. Artists will promote social participation, reflect social issues, and enhance community cohesion through public art projects. This trend will make sculptures not only objects of appreciation, but also a medium for social dialogue.

4. **Interdisciplinary cooperation**: Sculpture art will increasingly cross-border cooperation with other disciplines (such as science, architecture, design, etc.) to form new art forms and expressions. This cooperation can bring new creative inspiration and technical means.

5. **Personalization and Customization**: As consumers' demand for personalized artworks increases, sculpture art may develop in a more customized direction. Artists may create unique works based on customer needs to meet individual aesthetic and emotional needs.

6. **Globalization and Multiculturalism**: The process of globalization has made exchanges between different cultures more frequent. Sculpture art will absorb and integrate elements from different cultures to form a more diverse and rich artistic language.

7. **Digital Art and Virtual Sculpture**: With the rise of digital art, virtual sculpture and digital sculpture will become an emerging art form. Artists can create and display works in virtual space, breaking the physical limitations of traditional sculptures.

In general, the future of modern sculpture will be an era of diversity, technology-driven and social participation, and artists will continue to explore new materials, technologies and concepts in response to the changes and challenges of contemporary society.
