tells (among other things) a harrowing tale of a common mistake in technology development that blindsides people every time: the project that reaches an asymptote instead of completion that can get you to keep spending resources and spending resources because you think you have only 5% to go except the approach you've chosen means you'll never get the last 4%. It's a seductive situation that tends to turn the team away from Cassandras who have a clear view.

Happens a lot in machine learning projects where you don’t have the right features. (Right now I am chewing on the problem of “what kind of shoes is the person in this picture wearing?” and how many image classification models would not at all get that they are supposed to look at a small part of the image and how easy it would be to conclude that “this person is on a basketball court so they are wearing sneakers” or “this is a dude so they aren’t wearing heels” or “this lady has a fancy updo and fancy makeup so she must be wearing fancy shoes”. Trouble is all those biases make the model perform better up to a point but to get past that point you really need to segment out the person’s feet.)
