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?

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.

Harvard just open-sourced its entire ML Systems curriculum.
Free. Public. 6 pillars. Hundreds of pages.

And it won't get most data scientists any closer to a $150K AI role.

Here's why. Image
The book covers:

1. System Design
2. Data Engineering
3. Model Deployment
4. MLOps and Monitoring
5. Edge AI
6. Responsible AI
That's genuinely excellent material. Prof. Vijay Janapa Reddi built something worth bookmarking.

But here's what I've watched happen with 7,500 students over 8 years:

The ones who read everything and built nothing stayed stuck.

🚨McKinsey just dropped how to build agentic AI (that works)

Here's everything you need to know in 2 minutes: Image
1. Stop building agents; Start fixing workflows

The mistake every organization makes: falling in love with your new AI agent.

The solution: Identify the pain points in your process. Then use agents to connect analytics and gen AI into 1 seamless process.
2. Not everything needs an Agent

Stop agent-ifying everything.

Ask: "Is this a problem that actually needs solving with agents?"

Alternatives to Agents:

- Automation
- NLP
- Basic Gen AI
- Predictive Analytics

RIP Data Scientists.

The Generative AI Data Scientist is NOW what companies want.

This is actually good news. Let me explain: Image
Companies are sitting on mountains of unstructured data.

PDF
Word docs
Meeting notes
Emails
Videos
Audio Transcripts

This is useful data. But it's unusable in its existing form. Image
The AI data scientist builds the systems to analyze information, gain business insights, and automates the process.

- Models the system
- Use AI to extract insights
- Drives predictive business insights Image
