Sometimes I do like his videos, but this one was positioned so bad. The video does go over the changes in Plasma 6.1 and they are good, but this is not a huge change that would change anybodies live.
I know he is probably inspired by channels like Linus Tech Tips, but even they don't got that far anymore. I think he probably intended this in a comedic way, as most of his audience knows that he makes his videos like this, but it really makes the videos worse.
He also seems to make a video almost every day. That really doesn't help with the quality of the video's. I doubt there is a lot of time to do additional research on the topic, so often it seems to just stick to the basic information from some kind of article and comments (and maybe a few related articles). And is often just related to the drama of the day.
Although he does sometimes have video's that do require more research, but a lot of people won't see those as they assume low quality because of many other video's.
