The computer equivalent of doing the dishes while cooking is delegating tasks to "intelligent co-processors". When your computer wants to read some data from the disk it tells a disk controller "go get disk sector 2346". It then goes off and does something else for a while. Eventually the disk controller comes back and says "Here it is", and your computer pays attention to that.

So it isn't really muti-tasking in the computer sense, but delegation to specialized devices/services so that the general purpose CPU can do other things. Which is probably an important lesson on how to get things done.

For example I COULD put up the dri-wall for our bathroom remodelling project, but it is more efficient for me to hire someone else to do it, while I do something else.
