What’s the best example of using Objective-Cs message system at runtime that could not have been achieved at compile time? ChatGPT is giving me contrived examples or examples that could have been achieved with the knowledge of classes at compile time.

Portable Distributed Objects in NeXTSTEP. Send a message to an object that is actually proxied over the network to another server. https://en.wikipedia.org/wiki/Portable_Distributed_Objects https://en.wikipedia.org/wiki/Portable_Distributed_Objects

  Microsoft's COM+ was like, hold my beer. Why use a simple syntax when the compiler could quietly insert a bunch of magic and not tell you?

    Yeah, then came WinRT, to extend COM even further. And after 30 years, the tooling still sucks, even though WinDev loves it so much.
