"JIT PGO is adaptive to the workload that the process is experiencing. It is likely impossible to achieve this with AOT compilation. " Of course it's not :) You just generate different binaries for each use case. Truthfully, the "million machines/million use cases" story is pretty non-realistic these days (except in the above case!) Most people run mostly-specialized services for mostly-specialized use-cases. This is because it's necessary for performance in practice anyway.
