What are some disadvantages of Kotlin?

Here are some key disadvantages of Kotlin for Android app development:

1. Slower compilation speed: While Kotlin is faster than Java for incremental builds, Java is faster for clean builds[1][3].

2. Fewer Kotlin developers available: Since Kotlin is a relatively new language, there are fewer Kotlin developers compared to Java developers, making it harder to find talent[1][3][4].

3. Less learning resources: Kotlin has fewer learning resources and a smaller community compared to Java, which can make it more challenging for developers to learn and master the language[3][4].
