To be fair the Antichrist, being a prophesied entity from several millennia ago, is probably not super up to date on twenty-first-century business best practices. They probably still use waterfall.

There is a fantastic book to be written about the Antichrist finally rising to lay waste to the world, only to be astounded by air travel, the internet, etc. A demonic horde of a thousand flaming knights riding through Rome is largely written off as a new burning man thing, etc.
