With intelligent machines to do the thinking, will our brains get lazy?

Changing technology stimulates the brain and increases intelligence. But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent?
Artificial intelligence is taking over many human jobs. For instance, planes are being flown much of the time by automatic pilots. And the complex problem of controlling air traffic around large modern airports is also achieved by artificial intelligence that operates well beyond the capacity of mere human air traffic controllers.

Artificial intelligence is embedded in many features of modern life for the simple reason that intelligent machines can already outperform humans, including some aptitudes where there was once thought to be a human advantage, such as playing chess, and writing poetry, or even novels.

As machines get smarter, they will do more of our thinking for us and make life easier. In the future, the electronic assistant will develop to the point that it serves similar functions as a real living butler, fulfilling requests such as: “Organize a dinner party for six on Thursday, Jeeves, and invite the usual guests.”

At that point, our long struggle with challenging technologies is at an end. Like Be Wooster, we can take it easy knowing that the hard work of planning and organizing is being done by a better brain-the electronic assistant. Starved of mental effort, our brains will regress.
