I use Typewise, with its default hexagonal layout that's supposedly based on the frequency of letters in English. I've gotten alright with it - ~60 WPM on Monkeytype, which is enough that it doesn't feel clunky to use it. And it's quite fun to practice, too!
While I'm pretty sure it's quite possible to write faster with more predictive keyboards, I really appreciate the precision this one allows. Especially since I'm bilingual, which leads to autocorrect and swype getting quite confused sometimes.
I'm still in the market for a better keyboard app.
Another interesting one I've tried was MessagEase. It looks really cool and arcane to use, but I found it to be slower in spite of me putting more effort into mastering it.
You can use most modern phones as a spirit level with the right app! It's really useful when doing projects around the house, not having to run around to find a real one. Quite accurate, too!
Ehhh. I get that exploitative techbros and cryptobros have confused the issue by latching onto the AI bubble.
But at the same time generalized artificial intelligence is very likely possible and will be an absolute game-changer if and when it happens. It's easily of similar value to fusion technology.
And it is already bringing truly impressive results into reality - protein folding and diagnostic medicine come to mind.
Yes! There's so many cool apps on there! I wish the play store was similarly browsable.
