Are we living in or otherwise part of some type of Simulation or video game run by a computer, what are your thoughts?
No we are living not, we are living in a free world. If you don'tv believe in free will try and change your habits. For example, you don't like to eat fish, order fish next time for dinner. Life is crazy and real.
A computer program could be made in which we could have what we perceive as free will.
Look at things like Alpha Zero, that thing figured out how to play Chess and Go!
Computers are amazing.
If nothing else its at least good fun to think about.
