Ooo I like this ending a lot actually. These books have all had middle book syndrome but good payoff, for the most part now. We see how the first blade runner was created and why, lots of lore added to the universe with this one, in particular. It’s a fairly clever execution, because we know the system is broken based on all the other stuff, so it has to be something with holes in it. I think the writer did a good job with it.
