If you had the option to live in Cyberpunk 2077 for a week - in which anything you find you could take back IRL - would you?

Bring back literally any working implant with the documentation on how to avoid glial tissue buildup or the issues Neuralink is having with the hardware getting forcibly detached from any non-MS brain, you'll be an instant billionaire. I cannot overstate how seemingly insurmountable those issues are with modern prosthetics, the human body really, really doesn't like to play ball with any foreign material that's more complicated than a metal knee.

It'd be real easy, too. These things aren't trade secrets at all in the world of Cyberpunk, and Ripperdocs, like most passionate and highly-specialized professionals I've met, would likely jump at the chance to talk shop with someone who shows genuine interest in the thing they've spent their whole life learning how to do. Seriously, people absolutely love talking about the thing they're best at, I learned so much about how civil court actually works just handling catering at a law office and letting people infodump on me.
