How the hell do people type on "modern" keyboards?

I learned to "type" on a BBC Model B with four fingers and my thumbs for space, and although I can type properly I don't do it much because I'm faster the old way and my wrists hurt otherwise if I type for too long.

Modern keyboards have no tactile feedback - except pain because instead of hitting a key with some movement, I'm effectively repeatedly hitting the desk, they make a racket because I'm repeatedly hitting the desk, and there's no differentiation between keys to keep your fingers in the right place. They're little better than the "keyboard" of a ZX81.

Why? Just, why?
