It sounds like I'm one of a number of philosophy major who reads this site (and who works as a software engineer), and I'd like to second that philosophy can be a great major as long as you don't plan on being a philosophy professor (which, for most people, isn't an option). You can kind of take what you want from the major, so if all you want is to bullshit people that's what you might end up learning.

As for myself, I learned a lot about how to carefully construct arguments, how to make my arguments clearly so that people who disagreed with me could easily point out why they disagreed, how to critically analyze and (civilly) disagree with someone else, how to care more about getting to the right answer eventually than about being right in the moment, and how to be willing to change my mind when someone did make a well-reasoned criticism of my argument.

I studied mainly the ethics and political philosophy, rather than the more logic/cognitive science side of things, but I've still found it incredibly useful to my work as a software engineer. The process of breaking a complex argument down into appropriately sized chunks that say enough to be meaningful but little enough to be clear and (hopefully) self-evidently correct is incredibly similar to the skill of breaking a complex program down into parts that are large enough to do something useful but small enough to be correct.
