  • i… it’s a thought experiment. reasoning within the world of the comic requires some things to be taken as universal constants. here, those are “these people are trying to see over an obstacle”. while i agree the apple tree example is better, this illustrates the idea well enough within the context given by the comic. saying “the premise is flawed because of x” does not change the fact that the premise is right there.















  • it’s also because the smaller a transistor is, the more sensitive it is to cosmic rays. and there are a lot more cosmic rays in space than on earth. you can “rad-harden” them, but there are physical limits. as a result the most popular cpu architecture in space is the RAD750, based on the PowerPC 750 from 1997. the perseverance rover and the james webb space telescope are basically underclocked gamecubes, or those candy-colored imacs. like, perserverance runs at 133MHz and has 128MB of RAM.
