So, I work in tech and I may pattern-fit too much, but I feel some of it is due to PM culture in modern business and product development. In short, product teams in companies look for the best performing variant of products and once it determines it, it doubles down there. It only makes sense in terms of ROI for a business. In the grand scheme of things when whole industries do it, we as a society converge toward something, whatever category of product we're talking about (TV, suburbs, content algorithms, etc.).
