An old joke is something like, whenever you see an analyst describe a position as "unclear" or "with complications" or "beyond the scope of this book" then it's code for "I don't understand the position" heh.
And sure, it's definitely not very instructive to say "it depends on the position"
But sometimes (actually almost all the time) it really is beyond the scope of a simple forum post.
To properly learn how to handle two bishops, or bishop vs knight, you'd need at least something as thick as a book. 100s of pages, at least 100 example games, lots of analysis, and the person would have to take a few hours a day for a few months go over it all, then try applying it in games, fail, analyze those games, etc.
A simple forum post is never going to explain a topic people write entire books over.
And in any case "bishop vs knight" is more of a troll topic (or a topic posted by a total beginner).
In my opinion, the superiority of bishops realizes itself statistically rather than on the board.
Two bishops can out muscle a knight and bishop, but you'll basically never see someone U2200 with enough technique to pull it off.
That isn't always true
Yeah I was going to edit it to say "in some positions" but you replied really fast
