问答题 1.  Have you ever wondered what it would be like if machines could think? A few decades ago, such an idea may have belonged to the realms of science fiction, but nowadays it's not so far-fetched. As something of a tech junkie myself, I follow the latest advancements in artificial intelligence with great interest. AlphaGo is what is known as a "weak AI", operating within a predefined range with no self-awareness.
    Humans have yet to develop anything close to full artificial intelligence. Some scientists believe that true AI is impossible to create at present because humans "don't yet understand how brains work, so we can't build one." It's a valid point to make. Seeing all the advancements in science and technology over the past few decades, we still can't say for sure how perception works, where memories are stored or what really constitutes consciousness. Creating a "strong AI" will doubtlessly prove to be incredibly difficult. However, that hasn't stopped us from trying, and many tech giants have set up their own research labs.
