It's not the truth until it's proven to be true though. It's a possibility, however likely or unlikely.

The alternative is sitting around and doing nothing and waiting for this God-like AI to come into existence, but you'd look pretty silly if you threw away years of your life only for that not to actually happen.

I didn't say it was impossible, I said if it were true there would be nothing to do and thus no point in writing about that potentiality. It's sort of like writing about what mathematics should do if there was a thermonuclear war that wiped out all of civilisation.
