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.

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.

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.

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.
