It takes a few eggs out of our current basket and puts it into other nearby baskets, so as to avoid complete species failure if our original basket falls or gets dropped.

Not the most ideal solution, as we should really step out of our stellar neighbourhood to achieve lasting civilizational redundancy, but it’s far better than not taking any eggs out of the current basket at all.

Plus, incremental efforts in achieving civilizational redundancy always have better results than great leaps, both in terms of consistency as well as resiliency. Figuring things out a bit at a time is nearly always more effective than trying to solve everything all at once.
