Ask HN: Does the Facebook AI understands irony?

On September, 12 2017 I shared the following on my FB timeline "Irony : Americans strive to use Facebook Messenger Lite that has been develop for 3rd world countries." accompanied with the link to the HN comment : https://news.ycombinator.com/item?id=15222616 On Sep, 20 2017 I opened FB and there was the message on the top that said "Try Facebook Lite, our Fastest App". I have no doubts that these are two events are connected. The FB AI parsed my message from Sep, 12 and decided to show the FB Lite offer. But it's astonishing - is FB AI that good that it can understand this kind of posts?
