they can’t translate chinese, they receive a bunch of symbols and have a book with a bunch of instructions on how to answer based on the input (I can’t speak chinese, so I will just go with japanese for my example)

imagine the following rule set:

• If the sentence starts with the characters “元気”, the algorithm should commence its response with “はい”, “うん” or “多分” and then repeat the two characters, “元気”.
• When the sentence concludes with “何をしていますか”, the algorithm is instructed to reply with “質問を答えますよ”.
• If the sentence is precisely “日本語わかりますか？”, the algorithm has the option to respond with either “え？もちろん！” or “いや、実は大和語だけで話す”.

input: 元気ですか？今何をしていますか？

output: うん, 元気. 質問を答えますよ :P

input: 日本語わかりますか？

output: え？もちろん！

With an exhaustive set of, say, 7 billion rules, the algorithm can mechanically map an input to an output, but this does not mean that it can speak Japanese.

Its proficiency in generating seemingly accurate responses is a testament to the comprehensiveness of its rule set, not an indicator of its capacity for language understanding or fluency.

But it’s just a guy in a room shoving slips of papers around. He doesn’t actually speak Chinese.

Get it?
