| The issue with strong AI is not that "practicalities are unknown", any more than the issue with Leonardo da Vinci's daydreams of flying machines were that "practicalities are unknown". He didn't have internal combustion engines, but that's a practicality, other mechanical power sources already existed (Alexander the Great had torsion siege engines). They would never be sufficient for flight, of course, but the principle was understood. But he could never have even begun to build airfoils, because he didn't have even an inkling of proto-aerodynamics. He saw that birds exist, so he drew a machine with wings that flapped. Look at the wings he drew: https://www.leonardodavinci.net/flyingmachine.jsp That's an imitation of birds with no understanding behind it. That's the state of strong AI today: we see that humans exist, so we create imitations of human brains, with no understanding behind them. That lead to machine learning, and after 40 years of research we figured out that if you feed it terabytes of training data, it can actually be "unreasonably effective", which is impressive! How many pictures of giraffes did you have to see before you could instantly recognize them, though? One, probably? Human cognition is clearly qualitatively different. The danger of machine learning is not that it could lead to strong AI. It's that it is already leading to pervasive surveillance and misinformation. (idlewords is pretty critical of OpenAI, but I actually credit OpenAI with taking this quite seriously, unlike MIRI.) |
