You mean they cannot ?
I was under the impression that the purpose of computers cannot be fulfiled if we cannot get the result of computations out of the computers.

Haskell is not a computer programming language; Haskell implementations are not required to run on computers. Haskell is a formal notation for computation (completely unrelated to the Von Neuman machine sitting on your desk). It can be implemented on Von Neuman machines, because they are still universal Turing machines, but it is /not/ a radical attack on the problem of programming peripherals!

I suppose it can run on pebbles.

Any language can be emulated on pebbles; unlike most languages, Haskell can be compiled directly to them.

I know, and in this case one doesn't need IO.
The result is a nice collection of asorted pebbles.

Which is why Haskell treats IO as a domain specific language.
