Great series, very thought provoking on so many levels.
Not keen on the ending though - the idea of being downloaded into a storage tank, then being conscious forever whilst having no control over it, is terrifying to me. You could end up with your memories and thoughts streamed online, for paying customers to view, while having no rights over what the owners of the technology did, and no way of ending it. Hellish.
To me, the conscious identity = the soul. I hope that the soul can depart the body after death and live on a different plane. I hate the idea of technology putting a soul into limbo, but I doubt it would be possible anyway.
Re the migrant camps, that was worrying in a different way. It's likely that there will be many more migrants coming to developed countries in the northern hemisphere in future, due to climate change making parts of the world uninhabitable, along with a shortage of resources and rising civil unrest. How will the UK cope? If we take too many in, our systems could collapse, especially the NHS, so the whole country could end up in crisis. We will have to find a way of showing compassion while protecting ourselves - maybe well run camps could be part of the solution, but how easily they could turn into death camps, "accidentally". Frightening stuff.
