If you have the ability to position stars and black holes as gates for computation, then the same ability enables you to ensure that they are positioned so that tinier computation around these stars can happen not disrupted - the resilience is enabled by the fictitious future technology even if you don't use that gravitational complexity.

> All that computation gets condensed to 3 single numbers

> For a Galaxy computer on the other hand, blackholes could be the NOT gates.

i.e. in the worst catastrophic case the former carries more information (3 numbers) than the best case of the latter (one bit).
