Why am I going to use anything if I'm not trying to extract value? I don't mean in the sense of "make money off of lusers", I mean as in "do something that provides value for my effort".
I used gopher to "extract value" 25 years ago, but it turns out I want inline links and images and formatting and interaction (and compression and caching et al) because they're really useful. Look no further than HN for the Gemini ideal use-case, but even here the experience would be worse because of its restrictions.
Reading the spec, Gemini seems like it wants to be the elitist / hipster version of both gopher and HT(TP|ML). It forgets that a lot of user-agent features are pro-user, even if they've been co-opted for nefarious means. It's the CLI tech nerd's dream of a user interface, and discounts both the evolution of the web and of UI/UX design over the past 30 years.
