Why are the letter keys on the keyboard arranged obliquely instead of straight up like a grid?

Answer 1

On the contrary, I have heard that it is not so much for convenience, but is simply a legacy of typewriters and was created in order not to make a typo.

There were mechanics in typewriters, and it was simply technically difficult to place the keys exactly behind the others - from them, the levers should go to the initial letters.

I read somewhere that such an arrangement of keys, on the contrary, worsens the speed of typing, the keys are specially

The potential speed of typing on the keyboard in any case greatly exceeds the potential speed on any typewriter. And the nuances already depend on your personal abilities, and printing over the standard 200-300 characters per minute is not already available to everyone, because it does not bring noticeable advantages when typing.
The keyboard and the position of the keys on it is already a matter of personal habit. But I think that I can type my 400-450 on almost any keyboard, you just need to get used to it. And there you get used to special keys more than letters

Answer 2

If by "oblique" we mean that the letters are not in the center of the key, then this is done so that two letters can fit on the button at once (one above, the other below)

Answer 3

Why are the letters on the keyboard located exactly in that ...
And beveled or curved claves are like ergonomics, supposedly for ease of typing
