@care_save introduced this book to the Reading Suggestions thread about this time last year and I too felt it would be a worthwhile group deep-read and would make for a great comparative study of recent and past (and future) explorations. I posted this proposal unbeknownst to Caroline (I don’t know if this is what you meant by sponsoring others…!), but I think she can handle the pressure to take the lead on introducing this massive book and concept to the Café 
I will leave it up to Caroline to determine the content and the time for this Café and we can take it from there.
As previously discussed in other threads, such as the Patterning Language proposal, the current Café time slot need not be the sole, official Café time slot. I like @achronon observation that the Café need not be imagined as an institution but as a format. In my imagining, the Cosmos Café table is just a location in a fully public park with a dazzling menu selection open to anyone anytime and open to any ideas from anyone at anytime . . . just note that someone might have reserved a time to sit there (though you are still welcome to have a seat), so it good practice to check in with the communal calendar attendant (Marco or Doug) to see when a spot is open.
