I agree with the general premise that it is leadership's role in driving the strategic direction of how we approach such a controversial topic as automation that can determine the difference between success and failure, but Manna is too simplistic as presented. It treats the positive scenario as an easily attainable possibility; the reality will be much harsher even if somehow our leaders and countries could miraculously put aside differences and chose the altruistic approach. For example, in the "happy path" scenario presented in Manna, there is the assumption of resources being unlimited; this is made possible through efficiency and recycling, but look around you and it's pretty obvious humans of all types (regardless of race, religion, and economic stratification) are much better at wasting than saving, so this is a huge leap not only in culture but human nature. Manna too casually assumes humans will find a way to do the right thing, when it's obvious a fair number of us can't even find our butts with both hands.
That is not to say humans are hopeless; in the negative scenario Manna presents we see that humans have largely become mindless and complacent, living off the bare minimum. But humans are good at rebellion even in a world of seeming contentedness, and I suspect would be even more so in a world of false contentedness. Consider the Jews forced to work in weapons factories in WWII for the Germans. It was peaceful, as you'd expect it would be at gunpoint, but even then they cleverly found ways to sabotage the products they were building. So I think Manna has also oversimplified the dreariness of the negative scenario (isn't there is an entire series of popular action films about humans fighting machines?).
And yet I'd fully recommend reading Manna. I've criticized it for being shallow as a book but consider it more like a magazine article and it's a nice introduction to the fundamental differences in the way we approach automation; do we treat machines as something to augment humans or something to replace them?
Brain's story also mentions another controversial subject, that of Universal Basic Income (UBI). Automation and UBI are often debated together and for good reason; it's automation that will potentially make UBI both necessary and possible. How we approach this socio-economic challenge is a discussion worth having and Manna is an entertaining way to start. Proponents feel UBI is the way you keep a large, displaced, and angry population at peace, by giving each person "free" subsistence pay. People can live off it and are still free to augment it with voluntary work (assuming any is available), and the truly enterprising are also free to invest their time in innovation. Manna has an interesting take on UBI, which sort of exists in both the positive and negative scenarios but with key differences. In the negative one it's a minimal thing and exists much as you'd expect, as a form of allowance but as it's controlled by corporate interests it's something that is always being pressured to be as low as possible so the few that own the corporations can keep more for themselves. In the positive one it's less about cash and more defined in terms of resources; everyone gets an allotment of resources but because resources are treated as unlimited in this world (again, an assumption I consider a flaw) no one ever wants for necessities and everyone has some excess and it's really about how they want to utilize these excess resources (or not, for those that just want to sit around and watch Netfl...er, I mean, Amazon Prime Video all day). In this scenario Brain is certain there will be plenty of innovators and creatives to keep making the world better. I hope he's right.
We've all seen movies or read books where technology went awry and began to think that it knew better how to run the world better than humans have done - The Matrix, for example. That's what this book is about. It isn't a sci-fi masterpiece - in fact it's very short and simply written. It's more a cautionary tale - an effective one.
It begins with a simple program, not even an AI per se (or at least a simplistic one) that is installed at a fast food restaurant. The programs alerts employees when to empty the trash, was the restroom, and other menial tasks. Not only that, it tells them exactly how to complete each task, in what order, etc - through an earpiece worn by all employees.
When reading that I thought (and still think) that this is a feasable use of technology that could be implemented today to increase productivity and customer satisfaction. So many jobs are repetitive and trackable by computers, and they could be streamlined and improved greatly. I can think of jobs I have had in the past where I could hear a voice whisper to me what my next step should be when I was at a loss.
The problem occurs when computers began measuring one employee against the other, and gain power over personnel decisions.
One can understand, as a business owner, why such programs would be desirable. You care about your employees, but mostly you care about your own bottom line. In Manna, you see the consequences of taking efficiency too far. I won't spoil it, but it's quite terrifying. And if you doubt such things are already underway, simply read "I Was a Warehouse Wage Slave" in Mother Jones magazine, written by a worker at an Amazon-like warehouse, where computers tell you what to do, and how long they believe it should take to do each task, and the consequences of failure.
On the flip-side, the book also shows a society where technology works FOR humans, all equally, rather than for the bosses - those with enough money to get in on the ground floor of the coming robotic/AI revolution.
I was greatly inspired by this book. I would be interested to know if anyone is laying the groundwork for the second type of society outlined in this book. I understand the author is an incredibly wealthy man - perhaps this book is his blueprint for the future he will help to create?

This 2003 book comes in three parts. The first part deals with how it all started. Despite being written 15 years ago, the path is still very much futuristic. Automation has not yet caused the changes depicted in the book. But it is not hard to imagine that many workers will be become obsolete in this way.
The second part deals with the massive unemployment caused by automation. One solution is to warehouse all the redundant workers. Give them basic food, shelter, and entertainment. Force them to stay in the warehouse. Put contraceptives in their food so they don't breed.
The third parts deals with a much better option. I'll let you read the book to find about that!
