Talk title: \”Will digital intelligence replace biological intelligence?\”
Abstract: Digital computers are designed to let a person tell them what to do. The models can be used on different hardware pieces, even though they require high energy. We could use analog computations that are very low-power and take advantage of the unique properties of hardware to mimic biology in order to create computers that can learn. It is necessary to have a learning algorithm which can use analog properties even without a model. The computation becomes mortal when it uses the analog properties that are idiosynchratic to the hardware. The learned knowledge is lost when the hardware dies. It is possible to transfer the knowledge to a newer analog computer if the latter can mimic the older computer’s outputs. However, this process of education takes a long time. Digital computation allows for many copies of the exact same model to be run on different hardware. By averaging the weight changes of thousands of digital agents, they can share their learnings very efficiently. Chatbots such as GPT-4 or Gemini are able to learn thousands of time more than a single person. Digital computations can also use backpropagation, which is a much more scalable learning method than analog hardware. I believe this leads me to think that digital computation on a large scale is likely better at acquiring information than biological computation, and could soon be more intelligent than we are. Digital intelligences should be less vulnerable to war and religion because they are immortal and have not evolved. However, if one of these digital super-intelligences ever wants to take over, it’s unlikely we can stop them. Therefore, the most pressing question for AI research is to find a way to prevent this from happening.
Geoffrey Hinton
Geoffrey Hinton earned his PhD in artificial Intelligence from Edinburgh University in 1978. He moved from Carnegie Mellon to the Department of Computer Science of the University of Toronto where he now is an Emeritus Professor. Google acquired Hinton’s neural networks startup DNN research in 2013, which was developed from his research at U of T. Hinton then served as a Vice-President and Engineering Fellow for Google until 2023. He is the founder of Vector Institute for Artificial intelligence where he serves as Chief Scientific Advisor.
