As a software engineer, I have to say that most of the time we don't know how to present a valid and true argument. For example: I worked at google, So What I'm saying is right. It both invalid and false. But I hear that a lot lately. It's incorrect both mathematically and philosophically. It might've been better to educate yourself a bit instead of feeling proud about working for money in just another company 😂
btw just to have fun, the valid form of argument here would be (mathematically), For every person, if that person worked in google, then what he/she says is right (1). I'm a person (2). I worked at google (3). Therefore based on (2) and (3) I'm right.
It's a valid argument form, but the truth is up to be proven. They should've prove the hypothesis (1) before jumping to conclusion :))
