That's some real detective stuff. However do note that Satoshi is intelligent. And he could pleace fake clues so people can believe that and that
Satoshi may be the mastermind behind bitcoin but even then thats not to say that his spelling might be poor. Its a good idea looking into spelling as clues but even people i know from the uk get confused with spelling and use us versions over uk ones . Probably not conclusive proof.
Generally if someone excels in computers and maths they do poorly in English writing skills because they spent most of their time learning programming. Most medical doctors spend at the minimum seven years doing medical training, but most of them write in illegible handwriting on prescriptions. Satoshi is a genius programmer, but said his writing skills weren't as good as his programming skills. He's probably awful at spelling, and used the default US spell checker in his browser.
I can't say for sure because as far as things go I'm not a programmer, but I heard that the first version of bitcoin wasn't so well coded? Satoshi is a genius inventor. That doesn't make him a genius programmer. I might be mistaken though, because I really can't say for myself if indeed the earliest versions of bitcoin were badly coded or not.
Your post still makes me think about these teenagers referring to Kurt Cobain as one of the greatest guitar players of all time, though. There's nothing more wrong than that. Technically speaking the guy wasn't properly speaking nowhere but really, he wasn't so great. But he had a genius for song writing, though. He was truly a master at that.
All this to say that these things are generally not connected. Mastering a means of expression doesn't make you creative, and inversely, being creative doesn't make you a technical master.
Besides, I've found that non-English speaking programmers usually had a pretty good written English, on average. This has to do with the fact that almost all the relevant information regarding computing is in English and so they read English on a regular basis. It's the same for chemists, physicists, doctors, and a lot of other specialists. Besides, if they do researches, they usually like to publish their papers in English, regardless of their native language, because it brings the potential audience to higher summits.
(And also, doctors write badly on purpose, so that average people can't read what is prescribed
).
