this book is an impressive feat at condensing hours of interviews the author gathered with creators of "trans technologies" circa 2021 to 2023. haimson defines these as either being malleable/conducive to ambiguity (thus, "trans") or addressing problems concerning trans people practically, e.g. via voice-training apps. the themes he identified were interesting and he neatly lays out his point about the ambivalence inherent to trans tech, e.g. separatist vs. inclusionist tech, individualist vs. community-based/participatory design processes, capitalist vs. anticapitalist funding. he also references hil malatino's "trans care" and dean spade's concept of mutual aid. the book is critical of the exclusion of marginalized groups, whose problems designers aim to address, from the actual design process and voices some of the creators' qualms about the implications of their own technologies, e.g. accidentally creating new norms or only offering temporary relief from structural issues.
unfortunately, the book barely breaks out of an academic format; when reading large chunks at a time, the overview-quote-paraphrasing block structure of the chapters becomes tedious. i wish haimson had dedicated more of the book to setting up a wider theory of trans technology. at one point, he says that a more detailed discussion would warrant an analysis of labor he cannot provide. here, i wish he had brought in people from other fields to elaborate on points that fell short due to a mostly hci lens.
some of what i was missing from the book was remedied by the last chapter that presents outlooks on future trans tech and touches on murkier cyborg visions i was expecting in true paul-preciado fashion when going into the book. finally, he also points out the fragility of many highlighted projects and that many creators were (re-)inventing things that had already existed in the past. i would love to see more of a historical account of that, e.g. since hormone diaries or trans podcasts have been around since well before the 2020s. i also would've loved for the figures and screenshots in the book not to be grayscale, considering the book is, after all, about design.
