Yeah that's exactly the problem. It's an afterthought in the system. How certain can you be that the system you're using is compostable with any other code brought in to your system, even from libraries outside? In erlang, failure domains are the raison d'etre of the language, so everything in the ecosystem will play nice.

Ultimately, systems like akka are extremely complicated to get right, even for experts, because you have to think about all of the vm bits underneath. I can (and have) teach a junior programmer basic OTP concepts with the confidence that they can't mess things up. Now, they wouldn't be able to come up with the architecture I designed as a good idea, but I could tell them to implement it (with tests!) and expect them to get it right.
