@futurebird @jannem @dx Yep. (I used it as a starting point for debunking Elon Musk's Mars colony proposals, before he outed himself as a full-on Nazi …) You need to educate not only your entire work force but their teachers *and the researchers who will solve your as yet unknown problems in future* and the faculty who will keep the apparatus honest—so make that two or more rival universities!
100M people was my lowball estimate for a viable space colony with no long-term resupply.
