At first when reading the book The Expanse, I was very unfamiliar with a lot of theoretical space technology and other terms that were normal to many science fiction fans. I did struggle for a while and I had to make researches to understand a few things.
It was a struggle at first, but mostly because I had no prior knowledge to many things that might be considered normal to more educated people or people who are more familiarized with technology in many ways.
The responsibility of the writers is to provide enough for their stories to be understood, I supposed. That being said, many writers will not give all information for any sort of person to understand, but enough for the person reading to understand the things that can't be found anywhere but in the book. And it's most likely just fine.
Readers are supposed to fill the gaps of broad descriptions. Specially of scenarios and characters. Those, though, rarely make any difference.
