# From Punch Cards to ChatGPT By [ClockWork Crypto](https://paragraph.com/@clockwork-crypto) · 2024-01-13 --- My maternal grandfather, Skip, was always a farmer in my eyes. Tragically, my mother passed away from leukemia just a month after my birth in 1988. Being the first grandchild in the family, Skip and I were very close. As a child, I spent my days riding on the arm rest of tractors and combines during annual wheat harvest — and when I became a teenager, I worked the farm as a summer job myself. Yet, Skip’s earlier life was a far cry from the farming world I knew him for. Before I entered the scene, he had delved deep into academia, completing his PhD coursework in Statistics at Texas A&M, College Station, by 1972. Soon after, he embraced a professorship at the University of Maryland, finalizing his thesis in 1974. His groundbreaking research aimed at predicting and pinpointing safety and material risks in industrial settings. This monumental task demanded years of effort. He had to manually gather a decade’s worth of accident reports from diverse companies, process the statistics manually, and then convert these insights into [punch card instructions for the university’s computer system](https://en.wikipedia.org/wiki/Computer_programming_in_the_punched_card_era). Securing time on that computer was _not_ immediate; it required reservations made weeks or even months ahead. A single coding error could mean starting from scratch, potentially stalling his research by several months. He left that life in the 1980s to take over the family farm back in East Texas and branch off into entrepreneurship. But the desire to leverage statistical inference was baked into everything he did as a farmer — I just didn’t realize it as a child. To my child’s mind, Skip was doing “office work” as he called it — but in reality he was leveraging IT to forecast and secure financing to meet his operational expenses, optimizing chemistry in fertilizers to increase crop yields, developing strategies to reduce uncertainty in his cash flows through trading futures on the Chicago Commodity Exchange all on a [TRS 80 he bought at Radio Shack](https://en.wikipedia.org/wiki/TRS-80) with 16 KB of RAM connected to a dot matrix printer. Agriculture can be a terribly low margin business — and Skip’s bet was he could use statistics to level the field a bit. Over the years, the farm did not endure the test of time. Turns out inter-generational farming does not fare all too well when forced to skip a generation — and today’s input cost are more unforgiving than ever — economy of scale becomes the only way to compete profitably — and so most small to mid-size farmers from Skip’s generation were bought out and consolidated — but that happens gradually — little by little (at least it did for us). I, of course, grew to appreciate the strong connection between statistics and agriculture. I still remember the annual visit from the [U.S. Department of Agriculture](https://www.usda.gov/topics/data) meticulously sampling crop yields (on every farm, ours included) as part of their [National Agricultural Statistics Servic](https://www.nass.usda.gov/)e. Which provides, in my opinion, one of the great unsung and ongoing data projects in history — helping generations of farmers make “data-driven” decisions — before that was even a buzzword. But I found even more appreciation for all that Skip did decades later as I embarked on my own Analytics and Data Science career — my own second act after spending my 20’s and 30’s serving and globetrotting as a US Army Officer. I often reconnect with him over the phone asking him to recount how they used to run regressions or simulations or how they controlled for random sampling “back in the day”. And then occasionally telling him about how they are doing it now to gauge his excitement as I described to him concepts like machine learning, deep learning, reinforcement learning — — it is somewhat science fiction to him — but he _loves_ hearing about it — even if it isn’t quite _real_ to him this late in life. Enter the experiment. I decided over the weekend to _show not tell._ I wanted Skip to experience the new technology for himself — not just hear me talk about it. What if we could make a business plan to launch a hypothetical new farm in under 40 minutes? I could do it using ChatGPT 4 with the Advanced Data Analysis enabled, over screen share to his iPhone — we’d collaborate together to build it. We briefly discussed our assumptions: 1. We have 1,000 acres to farm in East Texas 2. We have $1M in start up capital to purchase equipment with 3. We need to secure a line of credit from a bank on year 1 operating expense to get started 4. We are interested in growing Wheat and Soybeans (what Skip actually farmed back in the day) We started simple: **Prompt 1:** “Write me an outline for a business plan to start a new farm in East Texas to grow wheat and soybeans”. Skip was immediately impressed with the long form results. But wait, we were just getting started… **Prompt 2:** “Give me a list of equipment I need to get started”**Prompt 3:** “Put it in a table and prioritize numerically based on what is most urgently needed to least urgent”**Prompt 4:** “now create a new column for budget allocation, Assume I’m going use a combination of leases and purchases, create an additional column to recommend lease vs purchase, assume I have $1M in starting capital.” --- *Originally published on [ClockWork Crypto](https://paragraph.com/@clockwork-crypto/from-punch-cards-to-chatgpt)*
