It doesn't have to. It will depend on the distance to the keyboard, the height difference between you and the keyboard, where on your desk the keyboard is placed. It also depends on the person writing ofc.

I type at 130 - 135 wpm with my fingers on the home row. I don't have a posture anything like that drawing. In fact I have to make a conscious and uncomfortable effort to contort my hands into that position. It's far more natural (for me) to curve my fingers to hit the right keys rather than curving my wrists so that my hands are perpendicular to the keyboard. Like this:

It's really quite easy to keep your fingers on the home row and avoid bending your wrists. I've done it for decades without any wrist problems.

It's even easier than the bent wrist position. Take a look at your hands. What is the shortest finger? Your pinky.

The straight wrist position lets you put your pinkies on the home row without the unnatural stretching that the bent wrist requires.

Try it: Keep your wrists straight and start by placing your index fingers and pinkies on the home row. Then let your middle and ring fingers settle into place.

You may notice that your middle and ring fingers arch higher than the index fingers and pinkies. That's fine!

Then start typing. If you're used to the bent wrists, the keys above and below the home row may not be where your muscle memory is used to. Keep at for a while and your fingers will re-learn where the keys are. Just don't let yourself slip back into the bent wrist position, and you will be back up to speed in no time.

Here's a comment from years ago with some crude ASCII art illustrating the difference:

I don't know. Hands on the home row is pretty comfortable for me. My arms are coming at the keyboard on an angle though, so there's no real wrist strain. Certainly if I kept my hands at a 90 degree angle to the front of the keyboard like in the diagram, it would be uncomfortable.

Many years ago, I was lucky enough to discover a keyboard training program called Stamina. The author suggested using a more ergonomic hand position: instead of placing your fingers on ASDF and JKL;, you place them on SDFV and NJKL. This way, your hands rest in a position similar to what you would use on an ergonomic keyboard. In addition, the characters on these keys are more frequent, so your base typing speed should increase (especially for cyrillic layout). It was over 20 years ago, and I wonder why nobody uses it and everyone still uses that uncomfortable orthodox hand position.
