The Kurzgesagt videos on these sorts of topics are interesting and entertaining, but they're often very speculative — they can rely heavily on unique but unproven theories, unprovable philosophical questions, or even just interesting sci-fi premises.

They're definitely informative and interesting within a given scope of discussion — it's good to ask interesting questions and explore what different answers might look like, because it helps us to push the boundaries of our mental models of the universe. But some of the videos — particularly the ones on Boltzmann brains or solutions to the Fermi paradox — are a lot closer to "here's an interesting thought experiment" than "here's something that's likely to be the case in our universe".

(Although they're usually very explicit when they do dive into this sort of speculative territory, and they also do a lot of videos which aren't in this vein at all — this is no slight on Kurzgesagt and the people who enjoy watching them!)

We’re essentially talking about the Fermi paradox. I think speculation is expected and the channel is upfront about their cited research.

Your comment could apply to any one commenting on these topics and so I am confused.

Yeah, I didn't want my comment to be a criticism of Kuzgesagt - like you say, they're usually very upfront when they do their more speculative videos. But I think sometimes people see the Kuzgesagt name and are like "oh, that's the informative science videos, this must be true", whereas a lot of the Fermi paradox stuff is closer to speculative fiction in nature than some of their other videos.
