Qwerty fucking sucks. This guy Sholes who invented the typewriter put no thought into the actual letter arrangement and doomed us to this disaster.
Dvorak exists and there's a new one called Colemak (now on windows) but they both have fundamental mistakes too. There are dozens of us on the other site debating keyboard layout design.
And for some education qwerty was originally alphabetical with the vowels on top.
https://youtu.be/blRn9U9Fapg?t=625s Pause the video. *Jamming was not an issue and was not a design point. That's common myth.
I tried to make the switch to Dvorak some years ago and got reasonably good at typing on it.
The issue was whenever I needed to input text anywhere that wasn't my PC at home. It turns out that basically everything uses qwerty and you'll never be able to escape it. Apparently I'm not wired in a way where I can use both.
That being said, I think steno keyboards are pretty neat and might pick one up to play with.
I solved this issue by getting an ortholinear split keyboard (keebio iris) and flashed it with custom dvorak layout. This way my muscle memory hasn't suffered much then using a regular keyboard with qwerty, only special characters like paranthesis cause issues.
Dvorak is an ISO standard and is in all OS's. You just have to switch the settings. They've apparently all added Colemak as well even though it's not ISO.
Admittedly I didn't watch the video but how can a keyboard with a different keyboard layout be considered qwerty, as in your statement "qwerty was originally alphabetical with the vowels on top". If it was laid out how you said they it wouldn't have even had the sequence "qwerty" so what makes it qwerty?
Colemak here. It was quite a pain to switch. Made my own called Middlemak that I think solves Colemak's and Workman's problems, it's on the other site.
Never used it personally, so theoretical: more changes than Colemak (big selling point was qwerty similarity), the LY same finger bigram, N and L with the vowels is too much consonant frequency on the vowel hand, personally not a fan of the L position (don't like the bottom row).
Typewriters actually sucked. The secretary's were typing so fast the old hammer looming keys would get all jammed together. Qwerty was invented to slow down and keep the most used keys away from each other. The Typewrites keyboard then became the easiest to hack onto a computer and here we are. I have a lot of utterly useless information in my head.
That's a common myth that's not actually true. With a spring return (still pre mass production) jamming wasn't an issue. It was simply arranged alphabetically, see video at 4:45 covers myths.
Most words (bigrams specifically) go consonant-vowel-consonant-vowel, etc. If it was designed to put sequences apart, the vowels would be on one hand and consonants on the other (which would actually be a good design, jamming or not).
