Do people actually have a hard time understanding Blindsight?

Apologies in advance for yet another Blindsight post but this has been on my mind for a bit. I see so many posts about Blindsight on this sub with the posters going on about how complex and dense and hard to understand it was. I saw one recently that called it a "philosophical stress test". And all I can ask myself is...really? Is Blindsight actually difficult or challenging to wrap your head around?

This is not even me hating on the book because I actually do like it quote a bit. It's very good (if a tad overrated) with some really interesting concepts. But at no point did I feel that it was anywhere close to "difficult" or hard to understand. Everything was pretty straightforward and explained clearly by Watts. It's definitely a bit more complex than something like, say, The Expanse or Project Hail Mary but it's not exactly something you need a science degree for.

Am I tripping or what?
