I don't type properly (use about half my fingers) but I find 80wpm is usually fast enough.

Using half your fingers is different from using two.

I can type with two fingers faster than I can type with full hands. I’m still trying to get my touch typing up to the speed of my two fingers.

I spent two years typing with just my forefingers, and can dk 80wpm with 99+ accuracy and I don’t look at the keyboard.

With two hands I’m still at 60-65 roughly and with worse accuracy but I’m sure it will come with time.

Doesn't sound real. I've typed correctly my whole life and have a lower WPM than that. You'd need to move your fingers at superhuman speeds to achieve that with just two wingers.

I spent literally thirty years typing with two forefingers, and note, I didn’t need to look at the keyboard. Also worked as a software engineer that whole time. So I had a lot of practice.

It’s why it’s taken me so long to try and adapt to touch typing. Too much muscle memory to rewire.

Sure, in the hypothetical where the person also decided to learn to type properly. If someone is plenty fast for their needs then it doesn't really matter, though.
