This wasn't a conventional war, Shepard says this. This is a war about survival. You broke your arm punching out cosmic gods. It's not fun. We're shown in the good endings life on Earth does survive. Do people even realize the difference between a 'dark age' and losing Mass Effect technology is?
Humans aren't going back to living in caves. FTL travel still likely works. It may take generations but society will rebuild.
As others have said, given the state of the galaxy at the end of the game, there is little difference between the ending and an ending where the Reapers harvest everyone: people who are still alive are basically SOL, but eventually organic life will rebuild.
Assuming the relay explosions do not destroy their star systems (and there is no reason to assume this given what happens in Arrival), in the Sol system, you have one habitable planet with severely strained resources, which was already struggling to support massive overpopulation; you have a biodiverse fleet with a variety of nutritional and environmental needs that is now stranded in the system (remember that travel across long galactic distances is only feasible with the relays; FTL only enables fast travel between
close star systems), with no way to meet those needs (meaning they will starve); you have a massive debris field hanging around Earth that will cause huge problems when it crashes; you have huge numbers of dead and wounded and no real facilities to accomodate them, because most of Earth's urban infrastructure has been destroyed -- and we know the Reapers targeted factories early on, so rebuilding will be difficult without any significant manufacturing capabilities.
The relays have been destroyed, meaning the comm buoy system is no longer functional (as per the Codex, they function by piping lasers through the relays), meaning that communication between distant systems is non-existent. Because of the way the extranet functions, vast amounts of knowledge have been functionally lost. As well, the galactic economy will no longer function, leaving local economies to collapse in the aftermath, without centralized governments to regulate them, because many government leaders are dead, missing, or stranded in Sol. There will be no external support for anyone, no trade, no emergency relief fund, nothing. With resources scarce, territorial disputes will errupt over shelter, land, food, even clean water -- and that is before luxuries like fuel and mineral wealth -- because it is too much to hope that everyone will suddenly get along just because the Reapers are gone; Shepard's sacrifice didn't change human nature. These are the kind of conditions that lead to civil unrest, riots, and
conventional war -- that is bad news for everyone.
And let's not forget the Gilligan's Island ending for the Normandy crew. Not only do they not have a relay, they don't even have a space-worthy vessel, so they are stranded without FTL, without any infrastructure or agricultural capabilities -- I hope Traynor knows about bamboo technology, because that's their only hope.
In the end, what is the difference between a "good" ending and a "Reapers harvest everyone" ending? Only the knowledge that the Reapers will
probably not return -- but that is not a guarantee, because we still don't know
who built the Citadel, who built the Guardian AI, or what tragic events precipitated the construction of the Reapers, and therefore there is no reason to assume that someone won't go, "hey, we should build a massive, omniscient AI to help us bring order to our chaotic universe", and start the whole thing over again. So no, there is no light at the end of the tunnel. Everything still pretty much sucks, for all the characters that we care about. That's not bittersweet, it's just bitter.
