With the most usual (Aristotelian) sense of the term "world", this

which is that I can be simulated by a computer program.

But then, as you were indeed driving at, we

going through your current state, and any notion of worlds

In the spirit of your thought experiment, let me ask
you a "personal" question. Assume you have big motivation
for going to Mars. You can now choose between a 100$ and a
10000$ teletransporter machine (TTM). Let us assume you are not so rich
that this difference count (or adjust the number relatively to your situation).
The 100$ TTM has no security and it is known that billion of copies of yourself
will be sold elsewhere, for example to the kind of "hell" you were pointing to.
The 10000$ TTM has quantum coded protection, so that the probability
is very near one that no pirate will be able to copy you.
Are you telling us that you will take the insecure low cost TTM ?
