> There's a long running pendulum that swings back and forth from FP. We're currently in an FP cycle. I think this is also happening because Functional Programming can really give us advantages, but also because it is very hard to understand fully (I am looking at you monads). We see how it can reduce: the complexity, the concurrency problems, or how we can code faster with it. But when we try to use it in a production environment, we give up because it's too complex. So you have this back and forth here in the field, between every wow moment with FP being all cool, and then being too hard to "get" or to use in production. Now I think we are getting there slowly. Trend after trend, we have more and more the main languages that are really incorporating FP principles. And not just as features. Plus many companies are pushing FP languages forward. Swift is a significant push for it that should democratize FP principles to the "masses", rather than a more "academic" crowd.
