BIG NEWS: #ChatGPT breaks #Python vs #R Barriers in Data Science!

Data science teams everywhere rejoice.

A mind-blowing thread (with a FULL chatgpt prompt walkthrough). 🧵

#datascience #rstats
It's NOT R VS Python ANYMORE!

This is 1 example of how ChatGPT can speed up data science & GET R & PYTHON people working together.

(it blew my mind)
This example combines #R, #Python, and #Docker.

I created this example in under 10 minutes from start to finish.
I’m an R guy.

And I prefer doing my business research & analysis in R.

It's awesome. It has:

1. Tidyverse - data wrangling + visualization
2. Tidymodels - Machine Learning
3. Shiny - Apps
But the rest of my team prefers Python.

And they don't like R... it's just weird to them.

So I wanted to see if I could show them how we could work together...
Let’s start with a prompt.

I asked chatgpt to find a data set that I used for this example. Image
...ChatGPT found it... Image
... And gave me this code to read the data... Image
I prefer the tidyverse, so I asked Chatgpt to update the code. Image
That looks better. Image
With the data in hand, it’s time for some Data Science.

I asked this simple question. Image
ChatGPT's response was impressive. Image
But, even though I’m an R guy, my team uses Python for Deployment…

In the past, that’s a huge problem.

(resulting in days of translations from R to Python with Google and StackOverflow)
But now, that’s 1 minute of effort with chatGPT.

Can I show you?
I asked chatgpt to convert the R script to python... Image
And in 10 seconds chatgpt made this python code with pandas and scikit learn. Image
ChatGPT did in 10 seconds something that would have taken me 2 hours.

But let’s continue.

The reason we had to convert to Python is for “deployment”

Deployment is just a fancy word for allowing others to access my model so they can use it on-demand.
So I asked chatGPT this: Image
And ChatGPT made me a Python API using FastAPI. Image
But this code is useless…

… Without a docker environment.

So I asked chatGPT to make one: Image
And chatGPT delivered my Docker Environment's Dockerfile: Image
So in under 10 minutes, I had ChatGPT:

1. Make my research script in R.

2. Create my production script in Python for my Team

3. And create the API + Docker File to deploy it.
But when I showed my Python team, instead of excited...

...They were worried.

And I said, "Listen. There's nothing to be afraid of."

"ChatGPT is a productivity enhancer."

They didn't believe me.
My Conclusion:

You have a choice. You can rule AI.

Or, you can let AI rule you.

What do you think the better choice is?
If you want help, I'd like you to join me on a free #ChatGPT for #DataScientists Workshop on April 26th. And I will help you Rule AI.

What's the next step?

RIP document extractors.

Google just released LangExtract: Open-source. Free. Better than $100K enterprise tools.

Here’s what it does: 🧵 Image
What it does:

→ Extracts structured data from messy text
→ Grounds every field to the exact source location
→ Handles 100+ page docs
→ Generates interactive HTML for verification
→ Works with Gemini + local models Image
What it replaces:

→ Regex/fragile parsing
→ Custom NER pipelines
→ Expensive extraction APIs
→ Manual data entry Image

Data science killed itself.

Not because AI showed up. Because too much of the field confused running a model with understanding one. Image
For years, data science rewarded people for producing outputs:

A model score
A dashboard
A notebook
A prediction
A nice chart

And a lot of that work looked impressive.
But underneath it, there was a problem:

No understanding of the business value (or lack of) it generated.

Someone built a free 7-week RAG curriculum on GitHub.

And they're right — it's good.

But, you'll need 1 more thing to get an AI/DS job in 2026: Image
Docker. FastAPI. PostgreSQL. OpenSearch. Airflow. Hybrid search. LangGraph. Production monitoring.

That's a serious architecture. Bookmark it. github.com/jamwithai/prod…
But here's what I've watched happen with 7,500 students over 8 years:

The ones who followed curricula stayed in tutorial purgatory.

The ones who built one real system — in front of a live instructor, with a deadline, with someone watching — shipped.

80% of data scientists say they want to build AI agents.

Almost none of them can answer this question:

Which agentic pattern should you actually use? Image
There are 7. And picking the wrong one breaks your entire workflow.

Here's the quick breakdown:
1. Parallel — multiple agents run at the same time. Use when tasks are independent. Faster output.

2. Sequential — agents run one after another. Use when each step depends on the last. More reliable.
