These are good practices to keep in mind when setting up GenAI solutions, but I'm not convinced that this part of the job will allow "data scientist" as a profession to thrive. Here's my pessimistic take. Data scientists were appreciated largely because of their ability to create models that unlock business value. Model creation was a dark magic that you needed strong mathematical skills to perform - or at least that…

I agree with your take.

I don't really see why evals are assumed to be exclusively in the domain of data scientists. In my experience SWEs-turned-AI Engineers are much better suited to building agents. Some struggle more than others, but "evals as automated tests" is, imo, so obvious a mental model, and can be so well adapted to by good SWEs, that data scientists have no real role on many "agent" projects.

I'm not saying this is good or bad, just that it's what I'm observing in practice.

For context, I'm a SWE-turned-AI Engineer, so I may be biased :)

I just spent yesterday applying Kaparthy's autoresearch on an ML problem. I teach ML for a living and was amazed with what the tokens gave back to me after many rounds of experiments. If Kaggle was still a thing, AI would generally beat it. The challenge I've seen is that most data science/ml modeling work is quite weak. Folks don't even know the basic tools well. Not sure if giving AI to them will really open up man…

I agree AI could probably do a decent job on Kaggle problems. Of course, almost no DS job is building models with well-defined objectives and perfect data. The DS and MLE folks I work with mostly spend their time reframing ill-posed product requests into ML systems that can be maintained and improved with feedback loops.

A _huge_ part of a DS is saying "No" to bad ideas posed by non-experts. The issue with LLMs is all they ever say is "Yes" and "Wow, that's such a great idea!"

I agree. It is difficult to convince leadership to do this work at all ("it works on my example, ship it"), and in my experience most DS don't even want to do it.

One of the key value is that it forces some thinking about what is the task you want to solve in the first place. In many cases, it is difficult if not impossible to do it, which implies the underlying product should not be built at all. But nobody wants to hear that.

Doing eval only makes sense if making the product better impacts something the business cares about, which is very difficult to do in practice.

I agree with you take the there isn’t a lot of specialist work for data scientists to do with using off-the-shelf LLMs that can’t be done by an engineer. As an AI-aware software engineer myself… this stuff wasn’t that hard to pick up. Even a lot of the work on the Evals side (creating an LLM judge etc.) isn’t that hard and doesn’t require serious ML or stats.

But aren’t there still plenty of opportunities for building ML models beyond LLMs, albeit a bit less sexy now? It’s not like you can run a business process like (say) AirBnB’s search rankings or Uber’s driver marching algorithms on an LLM; you need to build a custom model for that. Or am I missing something here? Or is that point that those opportunities are still there, but the pond has shrunk because so much new work is now LLM-related? I buy that.

I think there's a lot of methodological expertise that goes into collecting good eval data. For example, in many cases you need human labelers with the right expertise, well designed tasks, well defined constructs, and you need to hit interrater agreement targets and troubleshoot when you don't. Good label data is a prerequisite to the stuff that can probably be automated by the AI agent (improving the system to optimize a metric measured against ground truth labels). Data scientists and research scientists are more likely to have this skillset. And it takes time to pick up and learn the nuances.

Conversely, data scientists are doing software engineering, including webdev. It’s an interesting time. I think it’s less about the job title demarcation now, and more about output.

One thing data scientists brought to the table was statistical rigor in the models, but that seems to have left the building at this point with LLM-based solutions.
