The problem would be the resource would be too sloppy to be useful. For example, the phrase "Lipschitz: a space that isn’t too stretchy" doesn't tell you about the precise definition of Lipschitz, which is absolutely essential, and there are tons of names in math that would all be sloppified to "a space that isn’t too stretchy".

Not knowing precisely which definition you need for an application or which one you need for a proof to hold is essential for progress.

Math doesn't make up "jargon" for no reason. The names are to denote to professionals the least needed elements to make something true.

I always thought biology would be easier to learn if instead of entity names based on old languages they were instead verbose descriptions
