Alan Kay on Why is FP seen as the opposite of OOP rather than an addition to it (quora.com) 44 points by Philipp__ 8y ago ↗ HN
[–] dwenzek 8y ago ↗ I find this post a bit wordy but interesting. It notably points out well how the two approaches to deal with the state of a system, using versions or overwriting it, are in competition since a long time and in various domain of computer sciences.Alan also cites a paper about [Worlds: Controlling the Scope of Side Effects](http://www.vpri.org/pdf/tr2011001_final_worlds.pdf). A hot topic in the functional programming world. That paper makes me remember that ideas from FP and OO can mutually improve (an idea well developed in this short video https://www.youtube.com/watch?v=iSmkqocn0oQ.
