Another view on bots vs belts discussion. Certain logistic chests (Requester, Active Provider and Buffer) now cost space science packs to craft. Exact amount required is defined in startup Mod Options, default = 100 (i.e. you can craft 10 chests per rocket launched). Personal logistics still work, as you do not need Space Science for Passive Provider/Storage chests.
