So it starts as a line, explodes into a huge 2D complex mess, and eventually, after many generation, returns to form the same 3.7B cells long line? That's kind of amazing. I wish someone unpacked the units of abstraction/compilation that must surely exist here. Surely they aren't developing this with 1 or 0 as the abstraction level!
See here: https://conwaylife.com/forums/viewtopic.php?f=2&t=2040&start... It’s also a relatively sparse line, as the number of live cells is less than a hundredth of the line’s extent: https://conwaylife.com/wiki/Unidimensional_spaceship_1
Almost 10 years of development.
