I disagree with the notion that good quality content just doesn't exist anymore. Quality content will always exist and more quality content exists now on the internet than ever before now that it's become more accessible to more people than ever, but Google, Facebook, and Amazon have made this content more difficult to discover because their algorithms reward gamification with profit, incentivizing the production of high-volume and low-quality but highly-optimized content.
People passionate about sharing and learning will always be driven to produce quality content, even if they don't have an audience. The issue is that Google will never discover these people because they're only interested in discovering the best marketers on the internet.
