I agree with most of the recommendation in this article (thanks for publishing it!), but the advice about futures should be taken with a grain of salt. You need to be careful with futures because they swallow exceptions. However, the solution given (setting a global exceptions handler), while sound advice in general, doesn't actually solve the problem of hidden errors, as futures catch all exceptions and return them (so the caller can handle the failure in whatever way it prefers).

If your goal is "fire and forget" behavior (e.g. sending off a confirmation email), then it's better to use java.util.concurrent.Executors directly. It's actually easier than it sounds: https://gist.github.com/pesterhazy/c41786690ee0f8a3e5a21f88f.... Also see https://stuartsierra.com/2015/05/27/clojure-uncaught-excepti...
