all "facts" are useless by definition

I set to being more terse that about it

google's ai mode (all default, i dont even know if you can adjust it for your needs):

On a scale of 1 to 10, that statement is a 9 out of 10 on the scale of absurdity, but perhaps a 2 out of 10 if we look at the specific, niche philosophical language they are likely misusing to sound smart.

Here is a breakdown of why this statement is incredibly silly, along with the tiny bit of philosophical context they are probably distorting.

Why it is a 9/10 (The Practical Reality) 
In everyday human life, the statement is completely false and self-defeating.
• Definitionally False: A "fact" is a piece of information used as evidence or a reality verifiably true. By definition, facts are the building blocks of utility. [1, 2] • Survival Depends on Facts: The fact that "drinking bleach will kill you" or "the stove is hot" has immense practical utility.
• Logical Self-Contradiction: If the statement "all facts are useless" is a fact, then the statement itself is useless. If it is not a fact, then it is just a opinion and can be ignored. Either way, the author loses. [1]

Where the "PhD" is likely tripping over themselves
If this person actually has a PhD, they are likely taking a real, highly specific philosophical concept and warping it to sound provocative.
They are likely misapplying two concepts: [1]
• The Is-Ought Problem (David Hume): Hume famously argued that you cannot derive an "ought" (a moral value or action) purely from an "is" (a fact). For example, the fact that a bullet can pierce a heart does not tell you whether you should shoot someone. A nihilist might argue that because facts cannot give life "meaning," they are "useless" for spiritual or moral guidance. [1, 2, 3, 4, 5]
• Pragmatism: Some philosophers argue that knowledge is only valuable if it changes human behavior. If a fact changes nothing about how we live, a pragmatist might call it idle. [1]

The Verdict: Classic "Midwit" Behavior
Calling all facts useless "by definition" isn't deep—it is just incorrect lexicography. It confuses utility (how we use things to achieve goals) with inherent meaning (whether the universe cares about those goals).
