Interview
David Deutsch - AI, America, Fun, & Bayes
- Computers capable of faster-than-human thinking speeds will augment human cognition to overcome hardware limitations on speed and memory, rendering current speed constraints solvable.
- Hardware limitations on memory capacity may not be absolute if the laws of physics allow for extreme information density, though universal computers cannot simulate the entire universe due to insufficient memory and time, and self-simulation creates logical limits.
- Artificial devices could theoretically replicate specialized functions like mathematical insight or the feeling of love if the relevant signals and chemicals are computable, potentially allowing devices to augment individuals with severe brain damage or those who cannot naturally feel love.
- Transferring a human intellect program into an ape's mind is theoretically possible but would require intricate neuronal changes rather than simple hardware surgery; doing so would be considered highly immoral due to creating a person within deficient hardware.
- Current robotics cannot yet simulate sexual interaction between robots of the correct species, but such sophisticated devices are predicted to be created in the future.
- Narrow AI optimizing for specific objectives, such as stock market profits, cannot generate fundamental ideas like the concept of a smartphone, which is anticipated only by General AI.
- Certain traveling salesman problems are currently infeasible to solve within the age of the universe due to speed limitations.
- Human progress is not guaranteed and could decline due to parochial errors, with the possibility that specific accidents or mistakes could destroy civilization.
- Cosmological theories regarding finite matter or energy limits change on a time scale of approximately a decade, making speculation about asymptotic forms uncertain, while physics may or may not break down at the quantum gravity level of 10 to the minus 42 seconds.
- There is no proof that simulating a human brain is impossible, though it remains unproven until a working design is provided or the task is achieved.
- The American system of government is considered inherently flawed for dissipating responsibility and making blame assignment difficult compared to the British system.
- Theoretical physics has been stagnant since the 1920s, which prevented the invention of quantum computers in the 1930s and their construction in the 1960s.
- Future experiments regarding many-worlds theory may provide arguments that refute alternative explanations based on empiricism.
- Most lab leaks of pathogens likely occur when a worker leaves a facility after interacting with a pathogen, rather than through environmental leaks from the lab itself.
- Humanity is significantly safer now than 70,000 years ago, having survived a genetic bottleneck and avoided extinction events that would now result in only higher taxation.
- If a finite limit on GDP or computation exists in the distant future, humanity must decide how to utilize that resource for mathematics, music, or other endeavors.
- It is possible that a specific accident or mistake could destroy civilization, but the probability is not a law of nature, and every solved problem reduces the remaining risk.
- The American population classified as functionally literate level one (approximately 21 to 24%) likely faces software-related limitations rather than hardware-related ones, barring severe brain defects.
- Cultural circumstances can change a person's desire to learn, as evidenced by relatives who were forced to learn alien languages quickly due to migration, contrasting with individuals like Brett Hall who refuse to learn Mandarin Chinese despite having the hardware capacity.
- A specific unknown trait may correlate with IQ and influence how adoptive parents treat children, explaining why identical twins raised apart have similar IQ scores.
- Animals like wolves possess sophisticated genetic programs enabling strategy creation for unseen environments without requiring creativity.
- Simulated evolution involving humans could theoretically include suffering if hardware for personhood is initially used for the blind transmission of memes.
- Entering a virtual "experience machine" where one forgets their origin is incompatible with the search for truth because the laws of physics in such a world could not be the actual laws.
- Conditioning short-term goals by reference to a long-term goal is dangerous because if the long-term goal is incorrect, the error will not be discovered until it is too late to correct.
- Advice-giving establishes a relationship of authority that is considered immoral if not accompanied by a transparent argument.
- Defining "fun" requires a harmony between explicit, inexplicit, conscious, and unconscious knowledge that must all be open to criticism.
