I think this is a good description of how front-end development has become a "tool zoo", where new versions of libraries and frameworks are often radically different, and new libraries/frameworks keep popping up. I compare this to Python, where most of the time learning a new library will keep paying off for years and years. It makes front-end development an expensive (educationally) place to work, and the maintenance costs of the code are substantial.
