You are free to think anything, so say that you think that the body, blablabla, but don’t publish these kind of ass-producted idea like if they were definitely and universaly true !

I do think that the body is much more than a machine, simply because machines are created via human body and bodies weren’t created nor designed by any humankind.
Would we suffer if we were machines ? I guess no.
Our suffering is inherent to our humankind and to our bodies, artificially stop suffering and yes, you may become a machinekind, up to you.
