What do you want to do?

I want to record sound

OK, the computer is organised in terms of files and directories where a file is a chunk of information with a nametag like in an office filing cabinet, and the microphone is presented as an imaginary never ending file where the chunk of information changes every time you look at it, and you'll need to run a program to repeatedly look at the file and copy the contents to a new file in a directory of your choice... no, you can't put it "anywhere" and then search for it later, you are forced to choose a directory for it.

Your files have all the lines messed up? That's because it's built as if it's a typewriter with a forced "I'm at the end of a line" instruction which you never need to care about until you get a page from another typewriter where the operator had to push a different button at the end of a line and when he looks at the page it looks fine but when you look at the page you see it as if you had typed it on your typewriter pressing his end-of-line button which you don't have on your typewriter so it doesn't do anything, so you see one long line, ha ha!

Just as it isn't a full and knock-down criticism of GUI's to point out that people have done them badly, this attack doesn't go to the core idea of command lines, "type what you want to have happen." The available metaphors can and should be made more in line with how people think of what computers can do.

it's like math.

YMMV. Most of the HN population can deal with math. Some people's pupils constrict and their brains shut down.
