Can we just not?

Don't worry about it. Human brains are perfect and I'm sure these robots will never turn into serial killers.

Technically, it's the brains (image processing and recognition) that uses most of the power, not the eyes (camera sensors), but okay.

Human brains are perfect

Lol, no.

That’s the joke

Let's give em depression

because they want more human brains?

It's nothing dystopian like you think. Basically just a variation on camera sensors:

[...] bio-inspired cameras that capture the world more like the human eye does. These are called dynamic vision sensors, and they work like motion detectors for each pixel. They only “wake up” and send information when something changes in the scene, rather than constantly streaming data like a regular camera.

These bio-inspired cameras are also highly energy efficient, using less than 1% of the power of normal cameras.

Very nice and very impressive
