> CAD. Sure, you can do that in text... but it takes much more room to do and magnitudes more time to interpret.

Fascinating example for me. I do CAD... using text! My only experience with it is programmatic in openscad. We check the visualization, but only on output of the final product. For me it's dramatically easier to work with. That may be a personal defect but it's also consistent. Underneath the rendering is always data, which is text, markup, but strings of fundamental data.

And in science it's not a stretch at all that numbers come first. I'll argue you're reaching. Today no one is drawing their numbers from experiments directly on a graph. They record them digitally. In textual form typically, and then render them visually to obtain generic understanding. But also there, in the end, your conclusions (per tradition) need to be point estimates with error bounds expressible in concise textual terms. You may obtain them from looking at images but the hard truth is numerical, digital, textual.

I have tried OpenSCAD, but found it extremely limited and awkward. I much prefer parametric CAD like Fusion 360, OnShape (which I'm currently using) or FreeCAD (which has a really bad UX). And my day job is as a C++/Rust developer, so you would think that I would have good chances to prefer a textual representation.

Part of this might be OpenSCAD specifically. It is CSG based, which is really not ideal, making it hard to add things like chamfers and fillets to your model. Most OpenSCAD models I come across for 3D printing have a crude look probably because this is so hard.

But part of it is just that text for most people just isn't the right representation in this case. (If you look at the relative usage of parametric CAD to textual CAD on sites for 3D models you will see that I'm right. Also, look at what approach commercial packages offer.)

You may want to have a look at build123d. Its a Python library with an active and accessible community.

That does not mean that the CAD drawing itself is text. It is an artifact, produced from text. Using your argument you could just as easily argue that all computer code is text, and I don't think that's a useful redefinition of the word "text".

I'm absolutely fascinated by your answer!

Can you tell me more about the pipeline? Are you really starting from scratch by programming? You don't do any sketching first? I'm really having a hard time imagining doing anything reasonably complicated with this method. I'll admit that there are some advantages like guaranteeing bounds but there's so much that seems actually harder to do that way.

  > They record them digitally

Like I said, it is contextually dependent. If you're recording with digital equipment to a computer, then yeah, it's just easier to record that way and dump into a plot. But if you don't have that then no. And again, even recording by hand it is still dependent.

But some data is naturally image data (pictures?). Some data is naturally in other modalities (chemical reactions? Smell? Texture? Taste?). Yes, with digital recording equipment you can argue that this is all text but at that point I'd argue you're being facetious as everything is text by that definition.

  > You may obtain them from looking at images but the hard truth is numerical, digital, textual.
 

Here I think you have a fundamental misunderstanding and are likely limiting yourself based on your experience.

First off, not every measuring device is digital. So just that alone makes it down right false. And pretending all measurements are digital is just deceptive or naive.

Second, and I cannot stress this enough: *every single measurement is a proxy* to the thing you intend to measure.

You can't even measure a damn meter directly. You can measure distance through reference length that is an approximation of a standard distance (aka a ruler). You can measure distance through reference to an approximation of time and through the use of some known velocity, such as the speed of light through a given medium (approximating time, approximating c in the medium, approximating the medium). And so on.

What you cannot do is measure a meter directly.

And most of the things we're trying to measure, model, and approximate in modern science are far more abstract than a standard unit!

The idea that the ground truth is textual is ridiculous. That would only be true on the condition that the universe itself is running on a digital computer. Despite the universe being able to do computation, I see little reason to believe it is digital.
