A wonderful, thought-provoking post! I suppose that “taking these speculative and transgressive fantasies about science too seriously” would mean at least failing to look critically at whether they are even possible, given what we now know and are able to do. That is indeed an important task, although it is also a moving target–the fantasies of a few decades ago have been known to become realities. To that extent, taking them “too seriously” might also mean failing to distinguish between the monstrous and the useful. That is to say, one would take the fantasies too seriously if one accepted at face value the supposed non-monstrousness of the goal being advanced or (to put it another way) if one accepted the creation of monsters as something ethically desirable.
I’m grateful for Charlie’s comment — you should read the whole thing — not least because it gives me the delightful opportunity to pontificate a bit more on the moral implications of this sort of monstrosity.
There are indeed a number of technologies that are on the border of the monstrous and the useful. And, just as many things that decades ago were considered technically fantastic but are now realities, there are many practices that were once considered morally “fantastic” (i.e., monstrous) but are now widely accepted, such as in vitro fertilization (IVF, the technique for producing so-called “test-tube babies”) or organ transplantation. (Though these technologies have become broadly accepted by society, neither are by any means wholly uncontroversial or devoid of moral implications—many still find IVF morally problematic, and proposals to legalize the sale of organs for transplantation are a matter of ongoing controversy.) Scientists sometimes make what was once monstrous seem acceptable, but largely through showing that what is monstrous can be useful — meaning that a seemingly monstrous practice has some actual benefits, and that whatever risks it poses are relatively limited.
