I dont hate java (anymore), it has plenty of utility, (like say...jira). But when I'm writing golang I pretty much never think "oh I wish this I was writing java right now." no thanks
Theres a lot going on in Dune, not all of it is explained up front.

The movie ends up being kind of worse in this regard for people new to Dune
