Ceramic Bearings, are they worth it?

The topic of ceramic bearings in cycling components seems to be a timeless discussion.  In articles published first by road.cc in 2015 and then again in 2019, the topic of ceramic bearings has again been republished on 24 May 2020 by David Arthur. This article recently came to my attention, and I was quoted several times throughout the article, and I thought my readers may be curious to find out if I still stand by my comments that David Arthur used in the most recent article. My answer is, "yes". My opinion remains the same, and so here is a reprint of the article from road.cc written by DAVID ARTHUR @DAVEARTHUR SUN, MAY 24, 2020 14:00.  Following the end of David's reprinted article I'll add relevant information you can consider should you still decide to explore the marginal benefits of ceramic bearings.
