I wonder why Chrome's "Reading Mode" is not activated in Paul Graham's website. I really get used to read articles in Reader Mode, with the same style, background color, font size and without any other distracting elements of the page. His website font size is 13px, which is pretty small. So I copy+paste to Obsidian and read there.
