Completely OT: You know that phenomenon that when you hear a word for the first time in a long time or first time ever - and then you suddenly hear it again and again? Just happened to me with the word &quot;Fungible&quot;. I happen to know what the word means, coming from a financial&#x2F;trading background but don&#x27;t recall hearing it for some time now. Then 2 completely unrelated Hacker News articles I read, almost in a row, had the word &quot;Fungible&quot; in them - neither of which had anything to do with finance&#x2F;trading!<p>I know it is just random chance, but it feels really strange!
