They wrote about "places where the ecosystem is not quite as mature", and then referenced interacting with cloud services. I read that as alluding to the rapid development and instability of some cloud services. I've written plenty of non-FP code that interacts with less mature systems, and the problems I've always run into have been related to changing APIs and behaviors of the remote systems, not anything inherent to the language or paradigm I'm using. I was wondering what it is about FP that makes it less suitable for unstable environments.
