Oh, I don't doubt it, but... I do hope the author learnt better eventually. There's still time for the author to canonize the more watsonian interpretation of things this early in the story.Its the time honored manga author tradition of severely looking down on our ancestors. Believing them to be stupid cave dwellers with lacking knowledge and no interest in tasty food.
I don't know, I think it fits a chill story about isekai camping and self-growth fairly well.Mm, I'm not a fan of the time-line shifting. I would have preferred time passing between world transfers rather than him jumping a day into the future one time and the next jumping five years into the future with no clue how many times he's already "interacted" with people at that point.
For one, having a quick and simple "pre-made" friend group in the other world does allow one to jump right into chill mode, knowing anyone friendly you find is probably someone you've already befriended in the future, rather than having the story focus too much on that setup phase where the MC has to regain their footing in this new world (or fasttrack their way with silly overpowered skills). Not to mention there's that whole "gotta chill, enjoying the moment and every small interaction, because we don't know if we'll ever meet again" aspect to it.
And then there's the fact meeting all these strangers you've know you must have been able to befriend and get close with some time in the future is in itself a promise that "yes, MC-kun! you're going to manage to match your pace with others, develop your social skills and have some self-growth!". It does fit with the story's optimistic fairly well .
...Even if it means having to tackle the issue of fate and self-determination, and whether this self-growth was something you've accomplished tourself or something gifted to you by fate. But something that deep is probably expecting too much from this manga, more than I already am hoping for I suppose.
