Yea, haha, that was worded too strongly. Should have said "more folks are using Parquet for data workflows and adoption seems to be increasing". CSV is better when you need something mutable / human readable, so they'll always be around.

Main issue with Parquet is actually the metadata. CSV is nice because I can send it to a friend and they can instantly understand it; you can print it and understand it.

In contrast, Parquet is good for systems and I definitely recommend it in programming, but sharing.. not so much.
