A lot of the moral implications of Transhumanism fall along some pathways and not others.

Do you want to make a thousand copies of yourself, or do you want to have superhuman strength?

The latter is not actually that morally complicated compared to the former, but it’s still very much Transhumanism, unless you draw a boundary in which the body is a tool for tool use, and the mind is not, and thus the latter is functionally equivalent to “Humanism, but with powered exoskeletons.”

But for me, of course, it was never the forking that I was interested in, it was the youth, beauty, and power.  (Well, okay, intellect, too, but that still fits fine with no-brain-duplications limits.)

So a future where prosthetic robot arms and mechanical backup hearts exceed their native human capabilities, but upload civilization does not occur, is convenient for me.  All of the most terrifying implications of Transhumanism descend from the upload civilization bits, not the robot arms bits.
