There is no way to be sure that our sense experiences are 'real' as opposed to simulated by a computer

There is good evidence that this kind of technology is possible, even within a year or two

We, as humans, have a soul which can survive death.

Brian, whose brain is in the vat

The scientists who connected Brian's brain to the supercomputer

The surgeons who managed to salvage Brian's brain

The man who drove the truck that crushed Brian

We are running computer simulations

We are a brain in a vat

We are living inside a computer simulation

Philosophers are living in a computer simulation

It definitely doesn't feel like we're inside a simulation

All civilisations go extinct before they develop the technology to create 'ancestor simulations'

We can't make realistic computer simulations

Realistic simulations won't be possible for a very long time

It definitely doesn't feel like we're inside a simulation

Even if civilisations could create realistic simulations, they wouldn't want to

We can't make realistic computer simulations

Realistic simulations won't be possible for a very long time

It feels like we're inside a simulation

It's possible to create self-conscious 'people' via a computer simulation

There has probably only been one simulation created

Realistic simulations will be possible in the near future
