I am taking about this shit above (and and below), and only in the context of app development.
Whatever your sentiments to the craft of drawing may be, in terms of UI development, in the here-and-now, this stuff is almost pompous. Like most all the crap seen here except for a few. Most people under the age of 35, and many over that age, who are not illustrators themselves cannot even relate to drawings or sketches.
There is a distinction to be made. Very quick brainstorming notes like this example have their place. But not this grandiose old-school drafting shit. We do not have time for an “Ode to Past Masters.” You need to Agile-up.
