You can only feel sunshine and grass because your brain interprets sensory signals from your body. It’s easy to imagine a world where your cyborg body can deliver those same signals. If the sensation is the same, why would you _not_ exhchange your fragile meat sack of a body with a far more versatile mechanical one?

Mechanical devices don't repair themselves. Living bodies do. I think you underestimate the highly optimized and resilient nature of a meat-sack body.

Mechanical devices don't repair themselves.

Only because we haven't bothered building any that do. A cynical take would be that it would be bad for the economy.

We don’t yet know how to build self-repairing machines. That’s basically the same as creating new life forms.

[CamperBob2]

Well, creating life forms would require us to create self-reproducing machines, which doesn't seem like the same thing.

This will end up in a goalpost-shifting debate where the extent of self-repair capabilities necessary to qualify as "self-repairing" is argued. I'd say that a fault-tolerant system is at least 50% of the way there.

Perhaps, but imagine no need for surgery, no need for anesthesia, all wounds, illnesses and ailments fixed simply by switching the damaged part, or switching bodies entirely.
