You know how no one reads academic papers these days? Well, maybe they should EAT them! Here's the cookie version of our "better book" paper that lays out a new R&D model in education: researchers, developers, and instructors collaborate to continuously improve an online interactive textbook.

It's no @mcsweeneys.net but I got a letter printed in @economist.com www.economist.com/letters/2026...

I found your analysis to be empirically sound, but it would be sharpened by two refinements. First, ed tech is treated primarily as instructional software, but much of the industry’s scale and profitability comes from platforms and hardware (such as Chromebooks, iPads, and operating systems) that erode attention and degrade classroom behaviour even when no instructional software is running.

Second, educational apps may disappoint when they digitise tasks that are better done off-screen, especially for young children. By contrast, there are domains where computers are not optional but necessary, such as coding and data science. Separating infrastructure from instructional software, and distinguishing among different kinds of instructional goals, would clarify the economics of ed tech and the learning-science evidence.
