1. That's not really right. You're correct that "readiness" is important, but Python and JS are much bigger forces than Kotlin, and the main reason Java is getting features faster is because the investment in the platform has grown (and Kotlin was created when it was at an ebb). But so far, almost all linguistic features added after 1.0 -- generics, lambdas, type inference, ADTs, patterns -- are inspired by ML. 2. Java addresses those topics (where relevant) pretty much in the opposite way from Kotlin. Java rejected coroutines and is going down a completely different path with virtual threads; Java rejected data classes and chose to go down algebraic data types. So if you think Java gets inspiration from Kotlin, then it is in the form of what not to do.
