A short glossary of human irreplaceability
Postcard #42
Hello and welcome back to another edition of THE POSTCARD, Unregistered’s fortnightly roundup of recommendations.
Thoughts, tools, and treats
AI is a great opportunity to more precisely define what makes humans unique, in other words, to reflect on „the element of distance between what metrics give you and what you need to make a decision,“ as Hollis Robbins phrased it in her essay on „the last mile.“ So, instead of yet another lexicon of AI lingo, here’s a small glossary of terms that attempt to capture human singularity.
mētis
Many concepts and intellectual frameworks in today’s AI debate can be traced back to the history of ideas. These include judgment (Kant), the rule-following paradox (Wittgenstein), and the concept of mētis – a knowledge that enables humans to navigate the intricacies of specific situations and adapt to ever-changing circumstances, resisting standardization and therefore digitalization.
Tacit knowledge
The notion of tacit knowledge, put forward by the philosopher of science Michael Polanyi, points in a similar direction. Polanyi famously claimed, “that we can know more than we can tell,“ for instance, when an apprentice learns practical, implicit, even inarticulable knowledge by observing the master. Chris Walker concludes: „If we take Polanyi seriously, and I think we should, then we can make a precise claim about AI’s limits: if we cannot write down everything we know, then AI cannot learn everything we know.“
Process knowledge
Similarly, Dan Wang makes the case for experience and expertise that algorithms can’t capture, „all the things that come with learning-by-doing“ and calls it process knowledge: „Process knowledge is the kind of knowledge that’s hard to write down as an instruction. You can give someone a well-equipped kitchen and an extraordinarily detailed recipe, but unless he already has some cooking experience, we shouldn’t expect him to prepare a great dish.“
Local knowledge/context
In his latest article, Chris Walker revitalized Hayek’s classic argument against central planning, which claims that crucial knowledge is local and embedded in people’s practices. Walker argues that even if AI will someday be capable of digitizing contextual knowledge, „investing in codification quality upfront, maintaining it as domains evolve, and curating the right codified knowledge for each task“ will require „context engineering,“ which he defines as „experienced judgment about what matters, applied to an environment where AI does the processing.“ The whole piece is eye-opening: „The AI did the processing. The context engineering is what made the processing valuable.“
Taste
Another concept from the history of ideas gaining new prominence in the context of AI is „taste.“ E.g., last week Anthropic co-founder Jack Clark told Ezra Klein that „the thing that is increasingly limited, or the thing that’s going to be the slowest part is having good taste and intuitions about what to do next. Developing and maintaining that taste is going to be the hard thing. Because as you’ve said, taste comes from experience, it comes from reading the primary source material, doing some of this work yourself.“ To dig deeper, here’s a collection of classic quotes on the topic, and here’s a practical guide featuring literature as an example.
Noteworthy
“I wonder how many of the people making predictions about the future of truck drivers have ever ridden with one to see what they do? (...) These people have local knowledge that is not easily transferable. They know the quirks of the routes, they have relationships with customers, they learn how best to navigate through certain areas, they understand how to optimize by splitting loads or arranging for return loads at their destination, etc. They also learn which customers pay promptly, which ones provide their loads in a way that’s easy to get on the truck, which ones generally have their paperwork in order, etc. Loading docks are not all equal. Some are very ad-hoc and require serious judgement to be able to manoever large trucks around them. Never underestimate the importance of local knowledge.“
