In this paper, the invisibility of today's technology is often a blessing. Should invisibility be the guiding design goal for ubiquitous computing? The author mentions that invisibility is a narrow design goal. It's not necessarily a bad one, but it doesn't capture the full range of technological or creative possibilities. If the computer scientists and engineers only strive to build invisible systems, they will neglect to build important technology that is educational, engaging, and beautiful. It should expand the focus and rhetoric.
