"300 wpm seems a tall claim, but trained stenographers can attain that with steno machines (the closest analogue to this machine, as they are also "chording keyboards") According to a Quora response, court stenographers need to be able to chord up to 225 wpm:"Now, if you're talking about the steno machine; we don't type, we stroke the machine. If I recall correctly we had to stroke 180 words per minute in narrative; 200 words per minute in jury charge, and 225 words per minute in testimony."https://www.quora.com/What-is-the-average-typing-speed-WPM-of-a-court-reporterSee also http://www.openstenoproject.org/"

"> Each button is indented into the case to prevent accidental use (this would need to be tested)When this kind of testing is done, what does that look like? Do they make a mockup microcontroller that counts how many times a button was pressed, and then a test subject walks around with it in their pocket for a few days?"

"Lots of places are already supposed to do a similar thing with metal bottle caps: put them in a can and once the can fills up crush it closed."

"From a physics perspective, it doesn't actually provide any mechanical advantage: with a standard key, I can provide force on either side of the lever arm, so torque T = (2*F)*d. With their design, I can provide the same force on one side of a lever arm twice as long, T = F*(2*d). Same difference.I get the accessibility benefit though, that's nice."

"Is it just me or is every person in the pitch video wearing the same wig? This is wild. What is happening?"

"I recently started leasing a 2019 BMW i3 and it also seems to make this type of sound. Not my video, but matches my experience: https://www.youtube.com/watch?v=6Qe1wuDsXVk"

"Update: I've reached out to the creator and heard back: "The table will always be mounted from the right but we've tested the product with left-handed persons and there was no concern. It is wide and stable enough!""

"So are they only for right-handed people orrrr..."

"Make a positioning table! https://www.youtube.com/watch?v=_OnF6_V28DM I actually started down this road myself, and to get the bowling ball I just went to a local alley and asked nicely. They have lots of bowling balls that nobody's allowed to use any more (risk of chipping, or the finger holes are already eroded out)"
