I did recently learn of the https://en.wikipedia.org/wiki/Level_set concept, and it is a very similar concept.
> For all the history of computational mathematical visualization, graphing equations has been done in binary mode
These are very concrete, non-mystical claims. But do you really think "mysticism" is better here?
The millions of brightly-colored fractal posters adorning walls in the 80s are a very clear counter-example to your claim.
Your app is cool and the visualization is neat. The hyperbolic claims of originality really detract from that.
I think your critique would be more effective if you left out the part where you shame the author's lack of knowledge about level sets
I think it hides your valid (if overstated) criticism of the author's exaggeration behind a non-constructive insult, and your comment would be better without that tone
The point about level sets is entirely that the author not only does not have the background to make claims about novelty, they have all the clues they need to figure out that they don't have the background.
