In a not-so-distant future you will likely render your own reality and see / hear / taste what you want to without it actually being there.

With an external device that alters your brain signals, it’ll be as easy as putting on EarPods.

Gloomy but want to see sunlight? You got it. Want to see someone nude? Think it and it’ll happen. Only have pizza but feel like eating steak? Think it and your mind turns it into steak.

It sounds crazy but I think this may become a reality. It may take several iterations of a neuralink or some competitor.

It’ll be a toy at first, but as things improve continuously, it’ll be difficult to tell what is reality.
