Janet Rae Dupree suggests that since computers are already doing left brain tasks so well, it’s time for us to focus more on our imaginative, creative right-brains:

…now that computers can emulate many of the sequential skills of the brain’s left hemisphere — the part that sees the individual trees in a forest — the author Daniel Pink argues that it’s time for our imaginative right brain, which sees the entire forest all at once, to take center stage.

Wikis are good for the right brain, and the creative process, since they don’t bog you down with complex steps and processes – the domain of the left brain.

The absence of those left brain elements means you’ll be able to concentrate more fully on activities that require right brain thinking – for instance, adding your perspective to the document draft written by a colleague, and making sure that perspective takes into account the larger context of her contributions and the document as a whole.
