Do you want him to have any room on the carpet for himself?Why wouldn't he just print out all of Wiki[pedia and bring it on the magic carpet?
Better, but here's the thing. He was pretty good at his job and became good at reading people as a result of it, but he was prioritizing becoming a NEET with zero ambitions when he was preparing to come here. He doesn't need to improve the country to live comfortably in it, he's marrying into royalty and brought a bunch of comforts from home with him to help himself out staying comfortable until he adjusted to anything that is different here. He also didn't even know what things they would need to know specifically to do things like make glass if they weren't already doing it. There is a hell of a lot to prepare if you want to cover specifics, let alone all of the general knowledge of the human race. What does he prioritize? How should he gather it and transport it? Those considerations alone could have taken a lot of time.Yeah. Should have brought a library with him. Library genesis(more than a million non-fiction books) fits on 8 modern drives.
