Such a "speed limit" is an unfathomably bad idea, in every way, and moreover is a violation of fundamental human rights. I deeply oppose it. That is all.
The linked article from 1973 is very strange to read in 2026 and honestly it's hard to take seriously. It seems to actually argue that China and India should stop developing because development encourages dependence on energy. It says that machines are slaves that modern people are required to master?
The speed equity discussed in the linked paper has actually increased significantly as well. More people have cars, and more people can afford plane trips, and bicycle infrastructure is better all over the nation (the world, probably) compared to 1973. I agree with the general principle that cities should encourage diverse development so more people can choose not to use cars if they want, or if they don't have access to a car. In the paper, this would be achieved by somehow state limiting the amount of energy people would be able to consume per capita. I'm glad that world didn't come to pass.
Basically it sounds like the point of view of the article is that at some point the state should tell people they're not allowed to try to make a certain process more efficient in terms of time or resources, because that might drive demand for better productivity, which would be bad because it drives us further from nature and community. Some of the points intersect with beliefs I hold, but I strongly oppose this way of going about it.
In computing, waiting kills (indirectly, by wasting time). Speed is life.
Some roads have minimum speed limits. If we're talking about limits, that's the kind of limit we want.
Self-imposable speed limits like screen time limits and blocking services and proxies do exist already and certainly could reduce overall non-physical harm if imposed on everyone - but we struggle as a species to agree on the impact of non-bodily harms.
Artificial limits or more regulation might not be the answer, yet post-AI scarcity can lead us to interesting places.
How much faster should an ‚automated thinking‘ than a ‚manual thinking‘ be (allowed to be)?
