    -Furby was a toy that appeared to learn language but was actually pre-programmed with a set progression of phrases, creating an illusion of learning without genuine AI capabilities.

  • How close are we to achieving truly self-driving cars?

    -While there have been impressive demonstrations, true self-driving cars that can operate in any environment like an Uber are still many years away due to the complexity of handling outlier cases.

  • Is the Turing Test a valid measure of machine intelligence?

    -The Turing Test is outdated and not a reliable measure of intelligence. It only assesses if a machine can fool people into thinking it's human, which doesn't equate to true understanding or intelligence.

  • What is the difference between human intelligence and current machine intelligence?

    -Human intelligence is broad and flexible, capable of reasoning and deliberation. Machine intelligence, on the other hand, is currently focused on pattern recognition and lacks the breadth and depth of human intelligence.

  • What is the major difference in learning styles between human babies, primates, and current AI?

    -Human babies and primates learn about the structure of the world and how objects and people interact, building a model of the world. Current AI systems are primarily about learning correlations without this causal understanding.

    -Deep learning has made significant progress but faces challenges with truth and reliability. Despite improvements, these issues persist and represent a barrier to further advancement within the current paradigm.

  • How will AI change the way we work and live in the next decade?

    -AI is likely to impact jobs in commercial art and retail, potentially reducing the need for human cashiers. It may also exacerbate the spread of misinformation, affecting trust in society. The exact extent of these changes is hard to predict.

  • Is it stealing when generative AI produces algorithmic art trained on databases of human artists' work?

    -Whether it's considered stealing depends on societal and legal criteria. While AI does not have intentions, its direct use of human art to create new works raises questions about originality and intellectual property.

  • How are large language models a potential threat to democracy?

    -Large language models can be used to generate misinformation on a massive scale, potentially undermining trust in democratic systems and leading to uninformed decision-making.

  • Why do large language models work as well as they do, despite seeming like a 'dumb' way of generating text?

    -Large language models are sophisticated systems that go beyond simple prediction of the next word. They generalize from patterns in data, allowing them to generate text that is both novel and contextually relevant.

  • What would it take to make AI systems more truthful and logically consistent?

    -A paradigm shift towards neuro-symbolic AI is needed, combining neural networks with symbolic reasoning to create systems that understand and reason over facts for greater truth and consistency.

  • How much of AI's success is due to hardware advancements like custom AI chips and new architectures?

    -Hardware plays a significant role in AI's capabilities, but the current reliance on GPUs may not be the path to artificial general intelligence. Future advancements may require different chip designs or approaches.

  • What physical attributes of the human brain are missing in modern deep learning architectures?

    -Deep learning architectures lack the complex structure and variety of neurons found in the human brain. Each connection in the brain has intricate components that are not replicated in current neural networks.
