====A Complex AI: The Smart Coffee Machine====

Let's add some complexity to the system, and see what starts happening.

This time, we're building a smart coffee machine, and we're asking a different question - we want to know **how the user wants their coffee**.

There are many more inputs to the machine. 

^Input^Meaning^
|Hour|The hour of the day, in 24-hour time|
|Temperature|The outside temperature|
|Time Since Last Brew|The time since the user last had a coffee|
|User A|If this is Jenny using the machine|
|User B|If this is Carl using the machine|
|User C|If this is Amanda using the machine|

And our outputs are...

^Output^Meaning^
|Milk|If there should be milk in the coffee|
|Temperature|The temperature of the final coffee|
|Foam|The amount of foam to produce|
|Strength|The strength of the final coffee|
|Decaf|If it should be decaffinated coffee|
|Sugars|If the coffee should include sugar|
