There are at least three areas where I find his world view lacking.
First, its not historically informed. There was another astonishing period of progress and it did not end well: the broader GreacoRoman period. It was arguably even more revolutionary as it cultivated the basic mental modes required for science. Yet that world did not land smoothly on an s-curve, it collapsed completely. Yes, collapse is an accessible end-state today as well. If it turns out we cannot learn from the disasters of the past we have every reason to worry they will be repeated.
Which brings to the second point. You cant separate the scientific and technological universe from socio-economic organization. There are countless ways one can mobilize society for a while (eg slave labor that frees elites for higher pursuits) but long-term stable progress must, by definition, be based on fundamentally fair and distributive societies that dont chew on themselves.
Third, there are objective, physical and biological constraints that limit progress. The universe and our planet dont owe us a boundless canvas for us to realize any bizarre mental construct or obsession. What is on offer is already vast, but it does not extend in all directions. Learning to identify the naturally available growth options will be key for sustainable development.
I also think he misunderstands the role of digital tech. It is true that its impact so far has been marginal, even regressive, and pales in comparison to the major breakthroughs of 19th and 20th centuries. But its true nature is really human knowledge augmentation, similar to the invention of writing, the invention of mathematical proof etc. If we could liberate tech from the psychopaths and the sick economic system that supports them, it could lead to a enormous boost of global ingenuity and productivity. The tech dividend is still to be seen.
