You all vastly overestimate what AI can do. AI is just a tool which is useful for various things. Saying that AI virus will take over the world is like saying that MS Office will take over the world, because very advanced Office AI assistant will quit his job to plan World Domination. The very notion of "taking over the world" is 100% human-made. It's extremely anthropocentric. AI is nothing like human mind. It's just a machine. A lot of problems are completely not-computable. They can't be solved in any way by computers. All AI programs are constrained by this as well. Human mind will always be in general case vastly superior to any AI. Comparing general case strategic planning to chess programs is ridiculous. Chess programs use searching algorithms which are about as intelligent as binary search algorithm. General case strategic planning has no meaningful mapping to computing AT ALL. Not even in theory.
