He is a bit, but I finally watched the American vlogger that Dan idolizes (
https://www.youtube.com/c/Caseyneistatofficial/videos ) and it makes a lot of sense now at least to me. That vlogger has been at it for years and from the videos I watched, has been cocky for years as well. He's not exactly offensive but has done some stupid things on camera, has vlogs about luxury air travel, stupid stunts, etc. , not exactly the same as what Dan is doing but it seems to be rubbing off onto Dan.
It would be nice to see Dan back at his house finishing projects in the main living area and not at Lalande or in his mancave, but I guess that since he vlogs everyday that he just needs content wherever he gets it.
