My boyfriend doesn't respect my education?

Hey everyone! I want to know what you guys think about this situation.
He's a computer science major, and he also does electrical engineering. Super smart guy, and he's even building a 3D printer all by himself!
I am always so proud of him, and although I am not particularly interested in that field of study, I never question its relevance and always support him. (I do this by asking him questions, letting him know that he can always share good/bad news with me if something happens, etc.) I also make sure I give him hugs and kisses when he accomplishes something no matter how big or small.
But.
He seems to have little to no respect for my field of study. I am a Linguistics major, and he has said on several occasions that we are studying everything wrong, that we are outdated, and that our research questions are irrelevant. I have explained to him several times that we are super necessary for speech recognition softwares, helping people with speech problems, and studying ancient cultures to find out more about them (when we partner with historians). He doesn't seem to be "impressed" with any of it.
I tried to show him a 10 minute video on prescriptive vs. descriptive rules (look it up if you're not sure what they are~), and even though I was visibly excited, he basically said that it's completely irrelevant and that there is no "prize" to learning the rules that make up a language and then went back to coding.
It hurts me so much that he thinks this way about something that's this important to me. How can I make him realize that Linguistics is just as important as anything else? Is this normal for computer science majors or is it just him? Thanks!
