What ironic things do you think exist in this world?

There were many ironic things in the world, such as: Human intelligence and creativity can create many amazing technologies and inventions in a short period of time, but when faced with some basic problems and challenges, we often can't solve or make the right decisions. Some people in society always seem to be able to easily obtain wealth and power while others live in poverty and helplessness. Human culture and ideology are so diverse and rich, but we still have many different languages and cultural traditions, and there are huge differences between these cultures. In some cases, people will show extreme morality and compassion, but when they face some practical problems, they often choose not to take action to solve the problem. Human life and existence are meaningless because we live in a world full of stress and uncertainty, and our civilization and social system are often built on the pain and suffering of others. These are just some examples of irony in the world. In fact, there are many other things that are full of irony and contradiction.
