I don't know all the fancy names for logical fallacies but this seems to be deliberately misrepresenting the argument. The website clearly states that the problem with the Latin alphabet is that it has to be able to be written efficiently as well as read. Your trillions of humans over a few thousand years have had to both read and write this alphabet. In the past few hundred years we've had technology that allows someone who made a huge investment to produce massive amounts of text without writing, and in the past few decades the ability to produce text without writing has become completely ubiquitous. Does it still make sense for this alphabet to optimize for hand writing? Are you arguing that the constraints that made the Latin (or any handwritten) alphabet have remained unchanged over thousands of years? They want to redesign an alphabet to fit modern constraints. We consume a lot of text on devices that need to have screens that fit in our pockets. Perhaps a two-thousand year old alphabet isn't still the optimal solution?
I also don't think the authors necessarily expect to disrupt anything. They just made something cool and put it on the internet. I'm happy people like this exist.
