With people like Musk promoting the idea that the solution to our wrecking the earth's ecosystem is to decamp to Mars, this book addresses an important issue. I must say that I was not really satisfied with the way that it did that. It did not really address the issue of if the resources spent on colonising Mars would have been better spent on fixing the earth. What it does make very clear is that the problems on earth that are caused by issues like the greed and duplicity of people will be just as much a problem in a new colony. The people who leave for Mars fly around in private jets, apparently oblivious to their own environmental impact. (Incidentally, Airbus planes are made in Europe, not America, that's a strange mistake to make).

A plot is uncovered to kill most people, but they don't seem to feel the need to do anything about it.

It is unfortunately hard to imagine that with the level of environmental damage described in the book that there will still be any corals around in a few decades. They are vulnerable and close to extinction today. 
The book is quite funny in parts, with amusing digs at Tump and so on. It is easy to be read, although there are some rather long philosophical dialogues which got a bit tedious. It does not go into overdrive describing the new technologies which will inevitably have been invented in the coming decades. Rather strangely, it goes into great detail explaining how AR glasses work in a manner which is very close indeed to present-day technology. The author doesn't seem to have used their imagination much in thinking how things might have developed in the future. It is set in the future, but feels very close to the present day.
In summary, I am glad I read the book, but it was not great.
