Doing is not understanding. Even LLMs seem to know the difference.

I’ve written and spoken a lot about this (link to the talk). Naturally, the exchange here was too good not to share. Here is Claude in Cursor lecturing a user on the difference between having something coded by an LLM vs. coding it yourself so you learn and understand.

The better we separate things we need to understand from things we just need to do, the more effectively we will benefit from LLMs. We certainly can’t understand everything (nor do we need to), but it’s a good idea to avoid the illusion of understanding just because we can do it.

To paraphrase Feynman, we can only understand the code we can create.

If you woke up this morning running to the coffee pot even more aggressively because of the start of Daylight Saving Time, just remember that you’re not alone, and that’s how innovation and technological progress begin.

The world’s first webcam was invented in 1991 to monitor a coffee pot in a computer lab at the University of Cambridge, England:

To save people working in the building the disappointment of finding the coffee machine empty after making the trip to the room, a camera was set up providing a live picture of the coffee pot to all desktop computers on the office network. After the camera was connected to the Internet a few years later, the coffee pot gained international renown as a feature of the fledgling World Wide Web, until being retired in 2001.

You must be Platinum, Diamond, or Elite Plus somewhere. Maybe Premier Plus?

Since LLM developers discovered the idea of using multiple models (or agents?) that interact with each other to produce richer output, we have seen another round of semantic reduction by overusing “deep” and “research” (as we did with “intelligence”, “thinking”, and “reasoning”).

In this post “The Differences between Deep Research, Deep Research, and Deep Research”, Han Lee tries to make sense of the deep research mania and offers a quadrant to classify different models.

Is the “depth” of research just the number of iterations in the search for information? That’s another story.

I just received this email from Google. If you have a Google Workspace account, you may have received it as well. As soon as I saw the email, I remembered a Reddit thread from yesterday (where the meme is from).

I can’t turn off “Gemini Apps Activity” in my account (the account admin can’t turn it off either). Why is this? Why would I use a tool that is forced upon me while it is also giving me little to no control over my data?

See the Reddit thread here for more frustration with the haphazard rollout of “AI” tools (not limited to Google or privacy issues).

Sentence completion is a predictive task for the language model, not a causal one. It works as just another data model – it doesn’t need a world model, that is, unless a revolution is at stake.

World models are causal representations of the environment to the extent required by the tasks to be performed (as discussed here and there).

World models guide actions by making predictions based on this causal representation. So while not all data models need to be causal, all world models do.

LLM agents as world modelers?

LLMs are data models, so they are useful simplifications of the world. How well LLM agents can move from one useful simplification to another will determine the business use cases for which the agents will be useful. We’re about to find out.

Just came across this new, free book on the basics of enterprise data management. The book does a great job of covering the most important aspects of data management from a data science perspective.

I have a hard time fitting all of these tool-focused topics like using Git, CI/CD, Docker, SSH, OAuth into my course syllabi. These are things to know vs. understand and we focus on the latter. But these are absolute must-knows for data workers. This is how models are deployed and optimized for production, which is the only way to make a real impact. So this will be a great quick reference to list.

The book is a very practical introduction to (almost) everything that comes after modeling in data science. Here’s the intro to data connectors (no offense to data engineers):

Your job as a data scientist is to sift through a massive pile of data to extract nuggets of real information – and then use that information. Working at the end of an external process, you must meet the data where it lives.

CI/CD and Git:

The role of Git is to make your code promotion process happen. Git allows you to configure requirements for whatever approvals and testing you need. Your CI/CD tool sits on top of that so that all this merging and branching does something.

with the footnote:

Strictly speaking, this is not true. There are a lot of different ways to kick off CI/CD jobs. But, the right way to do it is to base it on Git operations.

I like the tone here (and the drawings). You can check out the book here.
