You can write about what your opinion will be for the future. Maybe there'll be robots everywhere, and technology will become more advanced. We might be already starting to colonize Mars and the Earth would have become even hotter than now. Oil and other natural resources will have dried up and the world will have to find a different way to get energy and generate electricity. The sea levels will be higher than now due to glaciers melting and arctic animals will become more and more endangered due to habitat damage. Popular celebrities will eventually die, some peacefully and others not so much. Music and fashion will be different, but it will probably still be enjoyed. LGBTQ+ might finally be accepted a bit more than now in society and black lives would probably have started to matter. Trump will never be picked again and the Corona virus might have gone away, but no one's sure about that. Many people will die and many more will be born.
I hope that gave you good ideas! Good luck!
