People are called to create content. The fact that they have found ways to monetize that content is a net boon to society, because it means we’re truly in an age where art and entertainment can be consumed and appreciated, while the artists and creators are able to focus on their content creation full time. A key defining factor of the renaissance era was that artists were actually properly funded and could focus on their art without being bogged down by a day job.
