Hmm, Rust and Kotlin are targeting very different markets. I can&#x27;t forsee Rust ever taking over much (if any) of the market that Java&#x2F;Kotlin&#x2F;Scala are going after, the cost&#x2F;benefit tradeoffs are just too different.<p>JetBrains&#x27; strategy with Kotlin is pretty simple - take the best bits of Scala whilst not allowing anything to compromise toolchain quality or seamless Java interop. The goal being commercial success rather than research papers. It&#x27;s basically a spin on the same recipe that made Java itself a success in the early days. Which is why I anticipate they&#x27;ll be quite successful with it.
