It's like writing on paper vs writing on a digital tablet. The difference in tactile feedback leads to better handwriting, at least for me.
I'm curious about the phenomenon they mentioned of "circles being smaller with markers". I definitely noticed that when teaching my overall font size decreased on markers vs. chalk, even when using the skinny chalks. But the effective tip size even with small chalk is larger than that of whiteboard markers. So I wonder if we had big ass whiteboards with big ass tips on the markers if the writing style would be more similar. Or if it's more a function of the resistance you get with chalk+chalkboard. Could we make a whiteboard+marker that had more resistance? Like some hall effect or something. Sounds too complex relative to just using chalkboards.
That being said, a downside I didn't see mentioned was chalk dust. I have asthma but still prefer chalk, but I did not appreciate having to pound the dust out of the erasers when I was in grade school. I wonder if they could make the chalk magnetic and have magnetic trap at the bottom or something. But again too complicated.

I think that whiteboard vs chalkboard is just personal preference/cultural, and that the explanations in the article are just trying to justify it (which is totally fair IMHO). So I don't think that there's any need to "fix" that problem with whiteboards.
My hand writing is poor and my handwriting with a stylus is worse but screen annotations on zoom have been life changing for me at work. I don’t really care that I cannot write legibly. Quick iteration on diagrams is king.

The Russian solution is to use water - wipe the board with a wet sponge.
The german way seems to be a wet sponge followed by a squeegee to wipe off excess water. Here's a masterclass from Frederic Schuller (and a rigorous advanced course in quantum mechanics)
In my school, the board was erased many times throughout the day with erasers, and then with water only at the end of the day so it would be "pristine" the next morning.
If you wipe with a sponge, you can't really go on to use it immediately can you? Like you can't write well on a moist chalkboard?
This discussion reminded me of my best Diff Eq prof. He would start each lecture by putting a small clock on his podium, and starting at the precise time listed for the start of the lecture. Then he would leap into action, chalk dust flying around him as he explained the subject of the day. He would often go through more than six full-size chalkboards, having a student erase a few chalkboards behind him so he could return to use the first chalkboard when he ran out of room on the sixth one. Then at the precise time scheduled for the end of the lecture, he would take the clock off the podium and leave the room.
You could often see him walking around campus, covered in a fine white dust, looking like a ghost.
It's been 30 years, and I couldn't remember his name, but man do I remember his lectures.
Update: after typing this, I searched for him, and unfortunately found him almost immediately. He just passed away, and there was a memorial to him on the front page of his math department: https://www.math.fsu.edu/DepartmentNews/Articles/Fac_Nolder....
I note this line from the memorial: His students marveled at his ability to draw a perfect circle on the blackboard with a single stroke.
maybe a wise use of technology?: never adopt a higher complexity tech when a lower one fit well.
And white boards are less clear (to me) and markers dry (often in the worst moment).
And about slides... very easy for prof, but i cannot copy a slide, always follow the reasoning, so having the things written is best, writing indeed is another side of thinking.
I enjoy using chalkboards so much more than whiteboards. Other than the chalk dust, I just can't understand how anyone would prefer whiteboards over chalkboards.
The fact that it's still used in many places obviously means it's not unbearable. Besides if you're bothered by the dust you can use the water cleaning methods described in this very thread. It's not perfect, but I would take a chalkboard over a whiteboard anytime.

Germans also squeegee their blackboards.

Here's to you, Dr. Nolder!

If it ain't broke, don't fix it
Chalk, the Emacs of boards.
I tried extending this analogy to dry erase boards, and all I could come up with was MS Paint

Yeah, it's the chalk dust. It's that simple.
Also different colors on whiteboards is occasionally helpful for clarity, e.g. color-coding an equation to a line in a graph. But that's pretty minor.
we had colored chalk for that purpose in my school for math at least

I had some teachers allergic to chalk. They sent students to pound the dusters on the balcony.
>Other than the chalk dust,
You know, the worst part that makes them unbearable and a literal health hazard to use.
