Firefox reader mode (necessary to read this, as the font size and color choices are poor) estimated this at a 30+ minute read. It would be a courtesy to readers for authors to provide a summary.

We're not there, and perhaps will never be, but I imagine a point where information organization becomes fully neglected because an AI tools can do something about it.
We have a taste of it with emailing that became a wasteland as we're supposed to filter and search it either way, and mail notifications have only a on/off button and nothing in-between.
Not reading emails is I think close to the norm, and I guess "TLDR" will stop being an expression and just a fact of life ?
