Google where I works at is largely a C++ shop despite Android Java.

AOT compilers exists for Java, Net, Javascript. I however doubt the user experience of those.

For example, GraalVM mentions the following,

"There is a small portion of Java features are not susceptible to ahead-of-time compilation, and will therefore miss out on the performance advantages. To be able to build a highly optimized native executable, GraalVM runs an aggressive static analysis that requires a closed-world assumption, which means that all classes and all bytecodes that are reachable at run time must be known at build time. Therefore, it is not possible to load new data that have not been available during ahead-of-time compilation."
