Kotlin's adoption in traditionally Java-dominated environments is gaining momentum due to its efficiency, interoperability, and developer satisfaction. Since being declared the official language for Android development by Google in 2017, Kotlin has seen widespread adoption, with 2.5 million developers using it globally. Strategic partnerships, such as the one between Spring Boot and JetBrains, further highlight Kotlin's growing enterprise viability. The language offers tangible business benefits, including reduced code volume, fewer bugs, and better compatibility with artificial intelligence, while maintaining Java interoperability. Organizations like Mercedes-Benz.io and N26 report enhanced productivity and developer happiness after migrating to Kotlin. Despite concerns about the availability of experienced Kotlin developers, the language's intuitive nature for Java developers facilitates quick upskilling, enriching talent pools. Overall, embracing Kotlin is presented as not just a technical upgrade but a strategic decision that aligns with modern technological trends, promising better developer retention and company image.
