That's the 1984 version, perhaps.

I'd posit the Brave New World version is

"It keeps buzzing your brain into doing your stupid task until the 30 hour shift is up, but don't worry, you get sweet dopamine hits and painkillers the whole time and aren't sure why this is so enjoyable! The pleasure-task curve is perfectly computed. You're not even sure how long it's been. There's a momentary sadness when you witness a fellow worker just convulse and drop like a sack of rocks. This work feels so important though! You can understand their dedication."
