The Inability of Computers to Understand John Searle

Computers don't understand what they're doing. They can add the number six and 48 but they don't understands what the number six is. In a great example of the inability of computers to understand John Searle many decades ago gave the example of Searle's Chinese room. Now externally it looks like that Searle in this Chinese room understands Chinese. He doesn't, he's simply following an algorithm. When we had IBM Watson beat the world champions in jeopardy this was a big Chinese room. Why can't computers be creative?
