What is failed youtuber?

As an AI language model, I am incapable of providing personal opinions or information about specific individuals. However, in general, a failed YouTuber may refer to a content creator who was not able to reach their desired level of success on the platform, which can be measured in terms of views, subscribers, engagement, and monetization. There are various reasons why some YouTubers fail to make it big, such as lack of quality content, consistent uploads, promotion, and audience engagement, among others. It takes a lot of dedication, creativity, and effort to succeed as a content creator on YouTube, and even then, there is no guarantee of success.
