CORBA got a lot of things right. But it was unfortunately a child of the late 80-s telecom networks mixed with OOP-hype.
So it baked in core assumptions that the network is transparent, reliable, and symmetric. So you could create an object on one machine, pass a reference to it to another machine, and everything is supposed to just work.
Which is not what happens in the real world, with timeouts, retries, congested networks, and crashing computers.
Oh, and CORBA C++ bindings had been designed before the STL was standardized. So they are a crawling horror, other languages were better.
