The futures aren't erased. I don't buy the single timeline hypothesis, it's completely inconsistent with everything we've seen in all except the first "Terminator" film and then James Cameron clearly decided he was not accepting that when he gave us T2. T1 Kyle's JD was in the nineties, erase that and therefore you have to accept the timeline rewrites its own entire history and therefore nothing counts anyway.
John jumped in Weaverbot's (and/or maybe JH/Cameron's) timeline or even into a completely another one given we don't know how the time bubble tech works.
In the final analysis, the only timeline that has to matter is Sarah's, it's "The Sarah Connor Chronicles." The one thing Kyle did know was the future was not set. What that seems to imply is that you're trying to spawn a better alternate future via a time bubble. What "Self-made Man" shows us is that the further back you go in time the harder it is to not blow things completely (go too far back and, for instance, your future includes a nuke war between USA and USSR before Skynet can be built, due to something you did - and what's left of the human race is back in the stone age and possibly heading for extinction in spite of the lack of Terminators).
