So CORBA is 33 years old now.
It used to be a really hot technology. But only 3 vendors left according to https://www.omg.org/corba-directory/vendor/list.htm .
The strange things is that nothing obvious has replaced it. If any: REST, a bit of protobufs, and Kafka maybe. All not necessarily any simpler.
@J12t CORBA-REST V1.0 was just published in September of 2023. There are still some folk working on this tech...
