Pseudoscience in Informatics

I often see individuals bashing mathematics as being nonscientific on /prog/.

How do you respond to the fact that branches which suffer from even worse practices exist within the field?

Like Bioinformatics ( heuristics and data mining data mining applied to something which is supposed to be an 4^3 wide instruction set )

or A.I. ( attempting of a invalid cybernetic transformation, hence the definition of a machine )

as soon as you want to go meta or talk about abstract/general properties, they become unusable, potentially inconsistent.
Why do you want to "talk about abstract"?

general properties
There's no sense in being precise, when you don't even know what you're talking about. -- John von Neumann, famous jewish rabbi

Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. -- Nikola Tesla, crazy experimenter
