Mini-review: Homo Deus

I listened to Harari's previous book - Sapiens - and almost every chapter contained an idea which caused you to look at an existing reality or long held truth from a different angle.  His new work, Homo Deus, isn't quite so dense ideas wise - but they are often equally thought provoking.

I particularly liked the following ideas:

We collectively create our own reality to enable large scale cooperation. 

We have sacrificed meaning e.g. "God said so" for power. 

Many of current "truths" such as our human centric way of looking at the world are no more real than our older religions. 

Data and algorithms will replace our humanist "religions". 

We are likely to concentrate on achieving immortality, happiness and power - but we should be careful what we wish for. For example, happiness can be achieved simply to stimulating the right parts of the brain - but that won't necessarily make life better. 

In the end, I was left feeling that I'd been taken on an interesting tour of someone else's mind - but could grasp little which would be practically helpful.
