Ok, as someone who was genuinely interested in Scandinavian history during the Viking Age, this one pisses me off more than it should, we know the vikings at BARE MINIMUM LEVEL OF CONTACT traded with people who traded with the Arabs, we know this because several viking hoards have been discovered with Arab coins.
Additionally, the Viking era came about because the vikings had (generally) better boats than other countries at the time, and those boats could traverse both river and sea, allowing them to trade over great distance.
There's a ton of other stuff I wont go into about the steel (which, by the way, was not damascus, nobody who spent any time learning about it would claim so), the broad terminology of "vikings", and the Ulfbert sword, maybe I'll come back some day and type it out, but I just don't have the time or energy to write an essay right now
youtube is plagued with these bots that either copy someone else's comment (normally positive of the video creator in order to avoid being auto deleted) or use some chatbot to come up with phrases, the picture is always some attractive woman or sometimes just straight up images from porn, when you click on the profile the banner image or profile links will contain a link to either a scam site or an onlyfans page. They generally also bot upvotes on their comments in order to get better visibility
