Nick Bostrom Simulation Quotes

It might not be immediately obvious to some readers why the ability to perform 10^85 computational operations is a big deal. So it's useful to put it in context. [I]t may take about 10^31-10^44 operations to simulate all neuronal operations that have occurred in the history of life on Earth. Alternatively, let us suppose that the computers are used to run human whole brain emulations that live rich and happy lives while interacting with one another in virtual environments. A typical estimate of the computational requirements for running one emulation is 10^18 operations per second. To run an emulation for 100 subjective years would then require some 10^27 operations. This would be mean that at least 10^58 human lives could be created in emulation even with quite conservative assumptions about the efficiency of computronium. In other words, assuming that the observable universe is void of extraterrestrial civilizations, then what hangs in the balance is at least 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 human lives. If we represent all the happiness experienced during one entire such life with a single teardrop of joy, then the happiness of these souls could fill and refill the Earth's oceans every second, and keep doing so for a hundred billion billion millennia. It is really important that we make sure these truly are tears of joy.

Consider an AI that has hedonism as its final goal, and which would therefore like to tile the universe with “hedonium” (matter organized in a configuration that is optimal for the generation of pleasurable experience). To this end, the AI might produce computronium (matter organized in a configuration that is optimal for computation) and use it to implement digital minds in states of euphoria. In order to maximize efficiency, the AI omits from the implementation any mental faculties that are not essential for the experience of pleasure, and exploits any computational shortcuts that according to its definition of pleasure do not vitiate the generation of pleasure. For instance, the AI might confine its simulation to reward circuitry, eliding faculties such as a memory, sensory perception, executive function, and language; it might simulate minds at a relatively coarse-grained level of functionality, omitting lower-level neuronal processes; it might replace commonly repeated computations with calls to a lookup table; or it might put in place some arrangement whereby multiple minds would share most parts of their underlying computational machinery (their “supervenience bases” in philosophical parlance). Such tricks could greatly increase the quantity of pleasure producible with a given amount of resources.

Leading scientists and philosophers such as Nick Bostrom, contend that if an advanced civilization created us, most probably this 'advanced civilization' is also a creation of an even more advance civilization.

Instead of trying to produce a programme to simulate the adult mind, why not rather try to produce one which simulates the child’s? If this were then subjected to an appropriate course of education one would obtain the adult brain.3

Suppose it required an enourmous amount of lucky coincidence to produce intelligent life, enough so that intelligent life evolves on only one planet out of every 10^30 planets on which simple replicators arise. In that case, when we run our genetic algorithms to try to replicate what natural evolution did, we might find that we must run some 10^30 simulations before we find one where all the elements come together in just the right way.

Philosopher Nick Bostrom takes things one step further by asking whether we are a “real” species or a simulation created by an intelligent civilization that came before. This idea comes from the simple fact that we will someday be able to create software simulations that believe they are real creatures. And when we achieve that level of technical proficiency, we’re unlikely to stop with one simulation of that type. In the long run, you could expect far more simulated realities than the real one that started it all. So the math of it says we are far more likely to be a simulation than an original species. The interesting thing here is that neither the real species nor the simulations would be in a position to know which one they are.

However, from our present point of view, it is not clear that creating a human race is immoral.

Superintelligence, Nick Bostrom estimates that 1058 human lives could be simulated with more conservative assumptions about energy efficiency. However we slice and dice these numbers, they’re huge, as is our responsibility for ensuring that this future potential of life to flourish isn’t squandered. As Bostrom puts it: “If we represent all the happiness experienced during one entire such life by a single teardrop of joy, then the happiness of these souls could fill and refill the Earth’s oceans every second, and keep doing so for a hundred billion billion millennia.
