Blog 8: Artificial Intelligence Everywhere

In today's world, it seems like artificial intelligence is everywhere. From the games we play, to the websites we use, to the systems governing our traffic and energy supply, artificial intelligence is everywhere. For this blog post, choose one example of artificial intelligence you interact with on a regular basis, and tell us about it. Some things you can include in your article:

• Who created it (or the first example of such a system)?
• How does it work? What algorithms or techniques are being used?
• What makes this system useful? Does it have any negative factors?
• How would things be different without this system?
• Is this system useful? Necessary? Overkill? Dangerous? Frivolous?
