Thanks for doing this; your criticism is precisely what I was thinking a few lines into the piece. To echo the other thing Douglas_Knight said, though, it's helpful to say something at the top that lets people know whether this is a worthwhile read for them. (For instance, the Scooby Doo post's title makes it pretty clear to most people whether or not it's the sort of thing they want to read right now.)
In this case, it would have been relevant to say that (in your analysis) the linked article isn't of interest for any quality insights, but mainly because it's been published in a prestigious journal and thus illustrates the (embarrassingly shallow) current level at which academics publicly engage with transhumanist ideas. (There are more deft/polite/high-status ways to briefly convey this information, of course.)
"Vulnerable Cyborgs: Learning to Live with our Dragons", Mark Coeckelbergh (university); abstract:
Breaking down the potential improvements:
Physical vulnerability
Material and immaterial vulnerability
Bodily vulnerability
Metaphysical vulnerability
Existential and psychological vulnerabilities
Social and emotional vulnerability
Ethical-axiological vulnerability
'Relational vulnerability'/'Conclusion: Heels and dragons'
Before criticizing it, I'd like to point to the introduction where the author lays out his mission: to discuss what problems cannot "in principle" be avoided, what vulnerabilities are "necessary". In other words, he thinks he is laying out fundamental limits, on some level as inexorable and universal as, say, Turing's Halting Theorem.
But he is manifestly doing no such thing! He lists countless 'vulnerabilities' which could easily be circumvented to arbitrary degrees. For example, the computer viruses he puts such stock on: there is no fundamental reason computer viruses must exist. There are many ways they could be eliminated starting from formal static proofs of security and functionality; the only fundamental limit relevant here would be Turing/Rice's theorem, which is applicable only if we wanted to run all possible programs, which we manifestly cannot and do not. Similar points apply to the rest of his software vulnerabilities.
I would also like to single out his 'Metaphysical vulnerability'; physicists, SF authors, and transhumanists have been, for decades, outlining a multitude of models and possibilities for true immortality, ranging from Dyson's eternal intelligences to Tipler's collapse to Omega point to baby blackhole-universes. To appeal to atomism is to already beg the question (why not run intelligence on waves or more exotic forms of existence, why this particle-chauvinism?).
This applies again and again - the author supplies no solid proofs from any field, and apparently lacks the imagination or background to imagine ways to circumvent or dissolve his suggested limits. They may be exotic methods, but they still exist; were the author to reply that to employ such methods would result in intelligences so alien as to no longer be human, then I should accuse him of begging the question on a even larger scale - of defining the human as desirable and, essentially, as that which is compatible with his chosen limits.
Since that question is at the heart of transhumanism, his paper offers nothing of interest to us.
