Elon Musk posed the question as the one he would ask an artificial general intelligence (AGI), but the exchange—and the simulation argument associated with it—does not establish that our universe is simulated or identify an external world.
Why did Musk ask, “What’s outside the simulation?”
In an April 2019 interview, Lex Fridman asked Musk what question he would put to an AGI. After pausing, Musk replied, “What’s outside the simulation?” Quote Investigator reproduces the exchange and traces it to that interview.

The wording makes the question sound as if a simulation is already established. It is not: Musk was posing a philosophical question about a possibility, not reporting evidence that our world is artificial.
What is the simulation argument?
The argument most often linked to the question is philosopher Nick Bostrom’s conditional trilemma. In a 2020 conversation with Fridman, Bostrom discussed the question in the context of simulation, anthropic reasoning and superintelligence. The argument says that at least one of three broad outcomes must hold:
#1 Best Overall
- Technological maturity is rare: Civilizations like ours generally do not reach a stage at which they could run large numbers of realistic simulations of their ancestors.
- Advanced civilizations do not run many ancestor simulations: Even if civilizations become technologically mature, they may choose not to create such simulations.
- Simulated observers vastly outnumber original-history observers: If advanced civilizations do run many simulations containing conscious observers, simulated observers could greatly outnumber observers in original histories. If we treat ourselves as typical among the relevant observers, that could make it plausible that we are simulated.
This is a conditional line of reasoning, not an observation that confirms any of its branches. The conclusion depends on assumptions about whether civilizations survive, what they choose to do, whether simulated beings can be conscious, and which observers count as a relevant comparison group.
Does technological progress show that we live in a simulation?
No. In comments reported by The Guardian in 2016, Musk compared the progress of video games—from Pong toward photorealistic 3D worlds—with the possibility that games could eventually become indistinguishable from reality. He said, “If you assume any rate of improvement at all, then the games will become indistinguishable from reality.” That was his extrapolation from technological progress, not a measured probability or scientific demonstration that our universe is simulated.
Rank #2
Even if a civilization could build convincing simulations, that alone would not show that it has done so, that simulated characters are conscious, or that we are among them. Those are separate steps in the argument.
What could be outside a simulation?
The cited discussion does not identify an outside world. Bostrom connects the question to the nature of a simulation’s creators, how it was set up and what might happen after it. He also raises the possibility that observers inside a simulation could face limits on understanding the larger context they inhabit.
Rank #3
As thought experiments, “outside” might mean an ordinary physical world containing the simulator, another simulation in a chain, or a kind of reality that does not fit our current models. These are possibilities to consider, not findings about what lies beyond our universe. In the sources cited here, “outside” is not a place identified within measured cosmology.

An AGI might reason through the consequences of a simulation model if given assumptions about how it works. But the fact that a system can analyze a hypothesis does not mean it can verify the hypothesis or inspect a world beyond its own observable environment. Nothing in the Fridman–Bostrom discussion demonstrates that an AI could access or confirm an external reality.
To distinguish a simulation from ordinary physical reality, an argument would need more than the possibility that sufficiently advanced technology could create simulated worlds. It would need evidence that favors one explanation over the other, while addressing questions such as:
- Empirical testability: Is there an observation that would differ between a simulation and ordinary physical reality, rather than merely being compatible with either?
- Consciousness: Would simulated observers have experiences, and how could that be established?
- Advanced-civilization behavior: Would technologically mature civilizations survive and choose to run ancestor simulations?
- Observer selection: What makes a particular observer “typical” among the possible observers being counted?
The 2020 episode outline flags these issues, but it does not report an agreed empirical test. Its transcript is automated, so detailed wording from it should be treated cautiously.
