Is reality an ILLUSION? Scientist says we may be living in a computer simulation controlled by an evil genius

Humans could be the subject of a science experiment
In reality, our brains are being kept alive in vat of nutrients in a laboratory
The nerve endings of your brain are connected to a supercomputer that feeds you all the sensations of everyday life

It's a questions that has baffled humans long before The Matrix; do we exist and what if we are living in a simulation?
While we have yet to have a definitive answer, one expert has waded through this philosophical quagmire to  explain arguments about whether we are just a brain in a vat.
Writing for the Converation, Laura D'Olimpio, Senior Lecturer in Philosophy, University of Notre Dame Australia, said we can at least be certain we exist.

Consider this: right now, you are not where you think you are. 
In fact, you happen to be the subject of a science experiment being conducted by an evil genius.
Your brain has been expertly removed from your body and is being kept alive in a vat of nutrients that sits on a laboratory bench.
The nerve endings of your brain are connected to a supercomputer that feeds you all the sensations of everyday life. 
This is why you think you're living a completely normal life.
Do you still exist? Are you still even 'you'? And is the world as you know it a figment of your imagination or an illusion constructed by this evil scientist?
