It is thought provoking at the very least. The perspective I saw his views on abstraction from is the perspective of the product itself. Imagine there is some perfect solution for the ultimate technology. It's a perfect whole, every operation has meaning and purpose, is as optimised as it could possibly be, the hardware and software blend seamlessly with no unnecessary redundancy and so on. Maybe such a thing is so advanced we'd barely recognise it woven into the very fabric of our biology and culture, who knows.
Our human limitations and abstractions limit our ability to approach this goal, so it's not so much that the idea of abstraction is bad because it's useful to actually get stuff done. But it's more that we should always keep in mind that abstraction itself is not the goal, it's just a tool we have to use to get there, because of human limits and I would also say natural limits (like computational efficiency etc).
Obviously such a thing of beauty is a hypothetical extreme. I can see this idea being useful on a smaller scale, like in organising a team, designing a product, or a piece of software, we should pay a lot more attention to where we draw boxes around our design space.
But I am kind of with you when it comes to the broader-sweeping implications. How far does this concept go, and what power do individuals have without some social techno-revolution to make any broader architectural changes to basically anything? I have a mobile phone that communicates via radio with centralised systems. These centralised systems exist to govern access and enforce payment for services, because that's how society itself is structured. Perhaps there's key value stores at various layers of this architecture. There is a store (again because money) where I can choose my own apps (because of human desire for freedom of choice) or view ads (money), all human constructs. (It's all becoming quite philosophical, another human trait.)
But is that the best possible solution for the problem of networked personal computer devices? Is mobile networked computing even an optimal solution for biological lifeforms, is it a technological evolutionary dead end or a precursor to some broader construct we're yet to discover, and if so then what do those superior structures look like from a design and organisational perspective? Perhaps on some alien world they have figured it out, and maybe their solution doesn't include radio communication or key value stores, or maybe it's something we wouldn't even recognise as technology, who knows.
What I take away from it is a call to think about why we're designing things the way that we do. Is there a way we can draw the design space differently and organise teams to consolidate or reimagine the problems they're solving in order to rule out truly unnecessary abstraction and keep only that which is necessary?
I can't imagine how it might look, but I am sure if someone figured out a more optimal way of organising hardware and software that served the infinitely variable needs of humanity securely and efficiently with less abstraction for the same or greater flexibility and that would continue to do so in perpetuity, that person would become rather rich (unless that solution made money obsolete, here we go again).
