Typst looks cool, and I'm probably going to check it out at some point, but a comparison to similar web-based LateX solutions would be more useful than what they have at the moment is all I'm saying.
The compilation speed of LateX doesn't really compare to Typst. With Typst I can work with 3 other students on the same paper, and all of our keystrokes are immediately rendered.
FTR, there are also many people who use LaTeX in a similar way...
(In fact, as I talk through this, I think the solution may just be to abandon the idea that attributes like bold and size are applied directly to text, and instead associate them exclusively with styles. Basically the migration from <b> to <strong> at the dawn of CSS, in WYSIWYG form.)
Ultimately you'd end up with a word processor that's harder to use but easier to use right. And no sales team will greenlight that.
But this entire discussion is predicated on a very prescriptivist viewpoint of the "right" way to use a word processor.
The bottom section especially, which is a list of Typst's shortcomings compared to LaTeX. This helped a lot when actually choosing this over Overleaf for the last writing project I had.
There are various “batteries included” markdown renderers - maybe like quarto - which add mermaid for diagrams and a few other features. But I’ve never seen a paper written in markdown with the same polish as what latex produces. It just doesn’t have the depth of features that you need for making a professional looking paper. Latex ships with all of that out of the box.
If their target market is people writing scientific papers, it makes sense that markdown isn’t in the list. Markdown isn’t a serious competitor.
Markdown is for convenient and quick "good enough" looking text editing. It is very good at what it is supposed to do, but the limitations are quite obvious.
Typst has its focus on editing scientific documents, something that Markdown was just not made for.
Ideally, unrendered markdown still provides a first-class reading experience.
I don't think Typst has that as a design goal.
But it is apples to oranges, you can properly format text to book editor capabilities with typst, while you can only do basic stuff with markdown.
