Poring over individual transactions sounds like a terrible, if not impossible, way to identify aggregate trends

You’re absolutely right and to be clear, my dad also pours over data roll-ups, charts, etc., but he’s never stopped looking at receipts. It’s a habit he’s had since the 70s. Back in the day, he used these electro-mechanical cash registers that had very loud typewriter-like receipt printers. At the end of the day, the manager would run the journal and my dad—-in his office across the store—tell you what kind of a sales day it was simply by listening to the sound of the register doing the end-of-day sequence.

There's a persistent meme on HN that it's straightforward to make a business that "runs on autopilot", with no human intervention. I'll admit that such a business is possible, but I'm deeply skeptical of the durability of such a business.

I'd much rather bet on a business owner like your dad, who's deeply involved. Sounds like your dad's receipt reading was a great habit to have, and paid dividends far outside of just "making sure things were running OK on a daily basis".

LOL, it's true. The idea of the quick exit is also part of the HN culture and I think that would be very foreign to people like my dad. People who build small but profitable, businesses and run them for the long-term are underappreciated in the tech world. I don't know about you but if I was building a SaaS, I'd be looking for the tech equivalent of In-n-Out Burger: something you build and spend most of your time making sure that it does the same thing consistently for years on end, and just enjoy the profits and dependability.

I'm right there with you. I've been building and running a job board for the last few months, and I'm hoping it becomes my own little SW equivalent of an In-N-Out. It's profitable, and slowly growing, so it's moving in the right direction.

Someday it'll be my own personal Double Double Animal Style.

Most of the time, the brain does this better than any machine.

That's why we don't have self-driving cars yet.

Unless you're Kim Peek you're not doing inventory or trends in your head.

Then you underestimate the human ability to recognize patterns.
