This seems like a meaningless argument. It's like saying:

"We are all just brains in vats in a giant floating supercomputer storage facility in space hooked up to a networked virtual reality system! Everything we perceive is false since the true reality is brains in vats! You think that's a snake? Nope, just an AI being fed to your vat brain by the supercomputer. There's no such thing as snakes."

There's no way to prove me wrong, but it's not a really useful thought exercise either. How does that help us solve the problems we want to solve?

For what it is worth, this is how I feel about many philosophical arguments. Personally, I enjoy thinking about and talking about these things but when it comes down to it they are not likely to affect my behaviors at all.
