Will WayTools' TextBlade make full-size Qwerty keyboards obsolete in mobile use? See this introduction: https://waytools.com/products/textblade/1/trailer

Will part of Jolla users switch to TextBlade? Will TOHKBD users start using TextBlade for fast typing on "mobile desktop"? What do you think?

I've not read the patent papers of WayTools and have not yet figured out all the functions of TextBlade, but perhaps this quotation of https://waytools.com/threads/blog/textblade-deeper-dive explains how a single key is used to replace 3 or 6 ordinary keys:
"MultiTouch Keys define TextBlade. The capacitive touch technology that made the iPhone possible is, for the first time, built into every physical key. Row upon row of 70+ plastic legacy keys have been simplified, and replaced by 8 ultra smart keys, powered by software intelligence that discerns user intent. The iPhone set a new standard for precise, responsive machines, and now physical keys are equal to it".
