Agree. The usage is the most important part. A knife itself is not a dangerous tool, but in evil hands it is. Same is with AI but it is more efficient and effective. Just like the atomic bomb was mich more effective than the usual kinetic weapons. That was, why the people worried about it. Amongs them Albert Einstein. But this example is not exact because the weapons cannot be used for peaceful purposes.

BTW: Elon Musk also worrying about evil usage of AI, see his words a few years ago.

About the neuron networks: I haven't heard about it but I'll ask my brother who is neuron scientist. Thanks for the info about this topic.
