Even if you're the type who thinks a Star Trek transporter is a transportation device rather than a murder+clone system, there's no reason to think the AI would have detailed enough records to re-create everyone. Collecting that level of information would be even harder than getting enough to extrapolate CEV.

So I suppose it might matter to the humanity it re-creates, assuming it bothers. But we'd all still be dead, which is a decidedly suboptimal result.
