This isnt an usolvable problem though since you can calculate the strength of model fit for a particular data point. You learn how to do this with linear models in stat 101 so everyone who is paid to be a datascientist will no doubt understand this.
Unfortunately the theory for linear models does not translate easily to deep learning based models, which this demo is based on.
The "strength of model fit" becomes much more complicated and is an active field of deep learning research.
It might not be an unsolvable problem, but it is a problem that is apparent currently in the technologies that we use.
