As for humanity's bleak future - one tenant of the terminator universe is the "the future is not written". Things can and are changed in the future by the actions we take today. That's why Skynet and the resistance send soldiers back in the first place. If the resistance fighters didn't belive that, they'd stop fighting and give up.
Wasn't the original reason for sending the Terminator back in time to kill Sarah Connor, because the machines were losing the war in the future and the resistance only wanted to ensure that John Connor lives and leads mankind to victory?
