Look ultimately more productivity - better for humanity, basically pie gets exponentially bigger.

For basically all of human history almost everyone you ask would almost always say, "in the good old days was better". People lived better life, better food, etc. It was never true.

Like certain data can swing wildly up and down in certain years like the crime rate, but if you zoom out almost everything is better vs 20 years ago for almost any time period and almost any country.

Now having said that since the 70s we got massively more productive, but quality of life increases were much less pronounced in the US context and most of the expanded pie went towards rich and ultra rich with only smaller bits and pieces to everyone else. But also who are these "rich" changed. And also the whole world on average is massively better today, incomparably better vs 20 years ago.

US is just at the peak of it, if you think about it, globally inequality between countries got smaller. Poor countries people started to earn significantly more, rich countries people ear slightly more.

I'd say it's fine. It should be like that.

So if say 10 years from now humanity is 100% more productive. The way the market forces work, it's just very unlikely the whole humanity will suddenly live worse, despite massively bigger "pie" size. I don't see realistic possibility of it.

It can of course happen in dictatorships like Russia, but look - it has already happened. It's the worst quality of life country in Europe. Despite massive fossil fuel revenues that dwarf what regular folks make country wide. If you give every Russian it's piece of fossil fuel revenue it'll be more money per person than minimum wage. Of course none of that goes to regular folks it all goes to Putin's friends - who use it to buy palaces and yachts for billions upon billions.

And yet even in this nightmarish scenario despite ever increasing inequality and ever increasing numbers of ultra rich Putin's friends in forbes list, massive amounts of property bought all over the world on stolen Russian money (stolen from Russian people)

Despite all of that the quality of life in Russia did not go down. (Surprise!) Yes its growth was slower than that of any democracy, but still it's not worse.

So I'd say at worst it'll stay the same if some horrible dictator comes to power in the US and worldwide.

At best we'll come up with the way to reduce inequality in which case our quality of life might increase even more than the productivity growth.

We are just innately pessimistic - which is a great survival strategy, but terrible for understanding how the world works
