Machines, AI, and the Most Important Question in the World
Message from 2024: I wrote this post in the spring of 2023, as AI tools were pretty new. I’ve since landed on the principle of not using AI generated images on my blog. This post has two images like this, but as it’s critical of the models (and explains a bit of why I currently don’t want to use them), I’ve let them be.
First, a very simplified history lesson:
For a large portion of the human existence, technology (often in the shape of machines or tools) has replaced manual labour, and led to increased productivity. The printing press replaced monks writing books by hand, looms evolved to include less and less manual laber per unit of fabric, the telegraph reduced the need for mail carriers, and photography really hurt Big Portrait Painting. Usually, the technology doesn’t completely replace the professions it affects. For instance, you can still get a tailored suit – but it’s a minor part of the clothing industry, and mostly reserved for the wealthy. The old turns into niches, hobbies, crafts and/or art.
Here are some of the positives from this:
The problem with teachers being tired of change
I’m going to try something that I know is impossible – talking about a profession as one entity. In Norway, there are 77,000 teachers, and of course, all of us are individuals. Still, there are some things I’m pretty sure many teachers agree on: We are tired of people with little expertise telling us how to do our jobs. The pendulum swings from one side to another, so what was in vogue 30 years ago is now considered the newest hotness. Be it politicians, parents, or others – many teachers want to be left alone, and be free to do a job they’ve many years of education and experience in.
But many have written about this before.
I would like to point at a problem this has led to. It has, in my view, created a sort of hardness in the profession that’s made us impervious to change.
🌱 Why 4k ≠ 5k
And what Apple means when they say «Retina»
I’m pretty sure the Apple Studio Display is overpriced. Still, the discourse after its announcement has been plagued by people not quite understanding the difference between 4k and 5k on a 27-inch display. It’s just one kay difference — why can’t you just buy a 4k screen that’s cheaper, brighter and/or has a higher refresh rate? Why do some Apple fans crave this extra kay so much??
Marc Edwards, of Bjango, wrote an excellent piece on this, and I especially like the visual examples of 4k vs. 5k on macOS. ** As a maths teacher, I find this problem interesting, and here I will bring some light to this issue the way I would to a high school class.** Perhaps this makes it easier to understand why the issues Edwards highlight appear.
What’s in a kay?
To narrow things down, I’m mostly going to look at 27-inch screens with a 16:9 aspect ratio (so no super-wides here!). Let’s compare the three most normal resolutions at this size: 1440p, 4k and 5k.
Humans are notoriously bad at comparing large numbers. Every day, there’s a new tweet trying to help us understand the difference between a million and a billion, by reminding us that:
- One million seconds ≈ 12 days
- One billion seconds ≈ 31 years
So, it’s forgiven that people think 4k and 5k are pretty close. However, 5k resolution has _a lot _more pixels:
