- Plover is a free, cross-platform steno software: https://www.youtube.com/watch?v=KZGuBV1xe64
- This Canadian guy develops cool, quality steno and ergonomic boards. The Georgi is $95USD - significantly less expensive than alternatives. There aren't any official reviews yet, but Plover users on Discord seem to really like it.

I'm planning to buy one this week - trying to get my boss to cover it since it will help with my mild RSI.
And if you don't like it, it's a QMK based board so it can be reprogrammed!
I've tried the "handykey twiddler" years ago and I just could not get motivated to practice enough to use the thing in real life.
For mobile use, the situation is is even worse because it requires the user to carry another piece of hardware in addition to the phone. Chording keyboards existed well before smartphones came on the scene, and the thinking was that you would have some type of heads-up/eyeglass display like Google-glass.
I guess it's just one of those funny things that people thought would be hot in the future but never materialized or turned out to not be desirable when it did.
If you assign common words or syllables to additional chords, then speed goes back up, but it becomes so much harder to learn -- so much memorization.
Stenographers (like in court) use a keyboard that relies on simultaneous keys (the chord principle, but still with more keys than fingers) to achieve speeds even greater than normal speech, with their own predefined combinations (tons of practice to learn) -- but unless you're transcribing speech in court or providing live closed captioning, it doesn't seem to be a skill worth investing in.
as an example, Matias' one-hand keyboard, in which half of the characters cost an extra keypress, had people getting up to 75% of their normal qwerty WPM 
I've never seen any study of a chording keyboard doing more than 70 WPM without a steno style multiple character output system
A bit cumbersome, but for conflicting sequences like that you use often you'd bind it to it's own separate chord (or bind Meta+Shift to a chord).

Like, if bn takes me to the next buffer, I wanted bnnn to take me three buffers over. I didn't expect it to be a dealbreaker, but over time it got more and more irritating to me.
I wonder how hard it would be to modify the package to work that way. I guess you'd have to make it so it doesn't actually insert a letter until you release a key to establish it's not being used as a modifier, which I'm not sure if emacs is in control of
Just in case anyone's interested.
If you're interested in bragging/chatting more about it, my email is in my profile. I'd love to learn about what you're doing.
However, it doesn't seem to be updated beyond 1994. And it's missing some things from Augment like the journal. But the system itself is nearly identical with augment regarding the commands and stuff. Which is why I bought the chorded keyboard so I can experience it engelbart-style.
Toying with the idea of making a version of this in pharo smalltalk because I think one of the things that makes augment great is the customizability of it. Like emacs, if it doesn't do what you want, you change the code inline while it's running.

I've always wanted to try one of these out but I'm not much of one to make it myself.
I'm struck my how similar this is to a discussion about using vim.
I’ve tried it a bit; not bad, but I can still type faster on my phone with my thumbs. One guy at my school (I think he helps develop this keyboard) has reportedly gotten up (or past) 60 wpm.
I just did a typing test on my regular phone keyboard and got 60. But maybe this will bring me up to desktop speeds. And if I get a physical corded keyboard, I'll go interstellar!
That said, the ergonomics of it are stupid amounts better than any keyboard. You can just wheel your chair back a bit and sit however is comfortable. Changing position while using it is much easier too since you're just holding it in your hand.
I should get back to practicing on it I think. The advantages would be enormous.
If you're going to learn to operate your bio-computer, please don't stop at typing faster, eh?

One of the basic "exercises" or "techniques" that people often do with (self-)hypnosis is to set up a simple binary yes/no signal from the subconscious mind to the conscious mind, e.g. a finger twitches for yes, wags for no (non-response is a kind of "does not compute, please rephrase" message.)
From there you can "leverage" the connection for more structured communication. E.g. the Six-Step Reframe algorithm https://gist.github.com/calroc/4719702 (deprecated in the 80's BTW.)
In re: these chorded input devices, the basic idea is that you set up with your unconscious motor programs to wiggle the chorded keyboard the right way, letting your conscious subjective experience be that of "pouring" your words from your inner voice (or imagery) directly to your machine.
Once you've got good communication with your subconscious mind, it's pretty easy. I used to do it w/ a just a Dvorak layout.
What about putting buttons along the sides of your phone and using chorded combinations as your passcode? Seems squeezing those buttons would be much harder to observe or record (intentionally or unintentionally).
Although calculating it this way will double-count some patterns which include long lines, I would say that there ar far closer to 9! == 362880 passwords. Even if long lines cut that space in half, 150000 more than meets your minimum of 15^4.
"Don't use your fingerprint to lock/unlock devices."
"Use a long passphrase to lock your devices."
Seems touch id and face id is exactly what security experts tell you not to do.
Those are recommendations for a specific group of highly targeted individuals in specific situations. It's not "basic security", it's "basic security for people who have such damaging information on certain subjects that they may be killed for it".
For the general population, TouchID and FaceID are more secure than the most common alternative (which tends to be no passcode at all) and secure enough that common criminals aren't going to bother with it.
Stopping nation-states from intercepting your data and using it as a flimsy basis for your murder isn't something an average person needs to worry about on a day to day basis.
