Typing on an iPhone today is just as error-prone as it was when the phone launched in 2007.
Next token predictors have largely solved this for day-to-day use.
Swipe + a more modern prediction model would mean we'd be able to type one-handed without looking at the screen at all, and have perfect accuracy.
We have the tech today. For whatever reason, nobody is using it. Why?
One just came out. Only one on the market I know of. It's called the Unihertz Titan 2, and I'm typing this comment on one. It's got a blackberry style keyboard and runs pretty close to stock android. I recommend swapping their default keyboard out with swiftkey, though the default one isn't terrible - swiftkey just gives me a few conveniences like emoji suggestions. It has play services, so it works.
Can't you connect one to your phone?
Yes, but that requires carrying a separate device, which makes it too inconvenient to use casually. I want the keyboard to be built into the device itself, like you used to be able to get.
There are keyboard cases like https://www.clicks.tech/ which attach to your phone directly.

This. Much of my typing speed and accuracy comes from feeling the positions of the keys. I can't do that on a touchscreen phone. They are so error prone and frustrating. Autocorrect is almost useless.
