Midjourney, a popular AI image-generator, has announced that it will block users from creating fake images of President Joe Biden and former President Donald Trump ahead of the U.S. presidential election. The decision is a temporary measure to prevent misuse of the tool during the election season. CEO David Holz emphasized that Midjourney is focused on exploring new mediums of thought and expanding imaginative powers rather than engaging in political speech. However, a watchdog group report revealed that Midjourney had performed poorly in generating images supporting disinformation and false claims of election fraud. The company's decision to block images of Biden and Trump aims to address this issue.
