the biggest issue is why would corporations willingly act as a working class life support and loose profits employing large amounts of people a specially in a country like the us where they have a very large amount influence and control over the government. Also purely government based ubi is actually a popular idea with some billionaires in the us like Elon Musk, Richard Branson,Mark Zuckerberg. So in a post laborer highly automated/ai dominated economy a more likely scenario is that the government recycles ubi through taxes in order to artificially create consumers and to stimulate the economy.

In my opinion there's probably going to be major geo political effects caused by climate change if the predictions are correct in Asia and parts of Africa. In the form of mass migrations due to drought and extreme temperature. We could also see major demographic shifts due to older generations dying off or straining the system in some places. On the technology side of things its almost guaranteed there will be increases in computer power and break throughs in quantum computing in the form of more efficient cooling and cores and higher qubit counts.AI is a wild card since its really hard to predict how disruptive its going to be. If ai can already make pretty good art and create code in multiple different language's at a decent level in 2022 who knows how advance it could be in 28 years with more data, better techniques/neural networks and super computers. That's my two cents.
