I don't believe the writer knows what YouTube's really place in our world is. Tik Tok is growing, but it will never have the inbound marketing support that YouTube has. YouTube is the number two search engine in the world and what matters to people most is that they are indexed. Google isn't going to give that away, its why YouTube and google have thrived during the rise of Facebook. And as Tik Tok rises and people go to search Google and YouTube will continue to be there. Plus add in the fact that Google is switching the search game which will benefit YouTube across all websites in a way we never seen before.

The writer here is looking at this from a social media stay point and not a online traffic point of view. Tik Tok will push Google and YouTube up over time. And Tik Tok will fall to the same place as SNAP and other generational apps.
