What about when I install a library or use a framework? When I use Spring Boot, it's calling my code. I install libraries which dispatch events to which I subscribe and that come with pre-defined objects I pass around. I use SDKs to talk with REST APIs. I even use objects that persist their data in my database, and have their own migration files.

I'm being somewhat disingenuous asking this. I realise most of the code in any application will be bespoke, but I don't think we should deny that the vision you describe has become reality in part.

Yes, it had became reality in many environments like .NET, Delphi and even Windows COM. The problem is however, they are only good in homogenous environments. Services on the other hand, could be easily consumed by all systems because they don’t need to know your system to work with and you don’t need to take care of the memory, threading and life cycle issues as you need to with objects.

In other words, it boils down to the objects vs interfaces, OO vs functional programming arguments in the last decades.

In reality, we still do both. But it’s clear by now that we don’t want remote objects anymore but remote services.
