Garbage collector in Kotlin makes it a no go for C or C++ displacement.

As someone that has left pure C++ applications in 2006, and has mostly written mixed language projects since 1999, usually the displacement is more religious than anything else.

In many use cases even if the performance is within the project delivery deadlines there will worthless discussions about performance benchmarks completly irrelevant to the task at hand.

And ironically many of the same folks are using Electron based apps for their workflows.
