>The proper comparison isn't the author's time versus the readers looking it up, but rather readers encountering a term for the first time having to look it up versus every other reader having to read overly verbose writing that reiterates basic definitions rather than getting to the novel points. If you're as interested in ROVs as you imply, well now you know for all of the other times you will read the term. If you're really expecting to never encounter the term again, I wonder why you're reading a technical engineering-adjacent forum.

This isn't a water hobbyists forum, nor one for all manner of remotely operated vehicles, so it's a bit optimistic to assume many people here will know "ROV" as a remote controlled submarine. Fact is, most of us cannot, from the title, figure out if we're interested, nor from skimming the first six (!) pages of a long article. Explaining ROV once at the beginning would, I dare say, not have impacted the enjoyment of underwater professionals very much, but saved me and most others on this forum some time figuring out if I want to figure it out.

I don't get this pigeonholing of the concern as being only about "water hobbyists" or "underwater professionals". It's literally just a type of machine you will become aware of some time during the course of reading about engineering or subsea operations. As I said, I'm not even fully sure it just applies to underwater vehicles yet I have bumped into the term/concept more than several times already in my life. If you're new and this is your first time encountering it, appreciate the learning opportunity. I bet you'll see the term a lot more now due to Baader-Meinhof.

And the article was not written to this forum?

This is a situation where HN’s “no editorialising titles” rule falls flat. Simply with the context change the title would be also best changed. I also understand why we have the rule of course.

Sure. There is a lot which could have been improved on the whole article with better editing.
