Here's one tiny example. Take Doctors (Medical doctors.) One of their frequent tasks is reviewing film from X-rays, MRI's, CAT scans, etc. The bulk of this work could be offloaded to an AI/Expert System, relieving them of reviewing film that the vast majority of the time shows nothing of value, and giving them more time to treat patients. Not only that, but expert systems can combine the opinions and experience of thousands of doctors, rather than just one and they'll do a better and faster job of it.

And that's just one tiny example. There are uncountable tasks and entire jobs that require people to do intellectual "grunt work" that could not only be relieved of this drudgery, but also saved from simple human error.

AI will revolutionize every part of our lives.
