You know, that one simple sentence would have done a lot to help me buy that part.
That would have been
better than the mass next-best-thing-to-suicide we got instead, but it'd still be rather silly.
Obviously, high-tech energy sources will run down, electronics will fail, etc., so if you really want to settle down, rather than, say, go back to the colonies and see what can be salvaged (as we saw, Caprica wasn't in bad shape all things considered):
1. You take a couple of the ships with the best combination of lifespan left / ease of maintenance, along with a handful of Raptors and Vipers, and prep them for long-term storage along with a supply of spare parts, to preserve your spaceflight and jump capacity.
2. Preserve your computing capacity - again, save the best computers along with the spare parts you'll need to run them for as long as you can. It's one of the few things you won't be able to replicate for a long, long time.
3. Gear down - start using your still-running technology to produce the tools you'll need to get started with and maintain a basic industrial-level society. Drills, files, saws, lathes, mechanical micrometer calipers, as much copper wire as you can make, nails, screws, etc. Crank them out while you can, so you'll have enough for the decades of playing catch-up that will follow.
