My pet theory is developers crave challenges. If their project is not challenging enough to stimulate their mind, they will introduce more and more complexities until the project is hard enough to keep them intellectually stimulated. Thus, software development will never converge into a single tech stack as smart developers that got bored as hell working on crud apps will invent new stuff to make their work more interesting and meaningful. In 5 years react and kubernetes will be considered legacy tech and we will march on to other new shiny tech.
