I’m sympathetic to the idea that philosophy as its own focus/major should be shuttered. If you’re doing “philosophy” and you’re being careful and intellectually honest, then you can probably do it in the math department.
We could pretty much save the world with fission today, but we don’t because politics. I’m not confident that we’ll actually adopt fusion even when the tech is ready.
I’d love to teach high school math or physics (or hell, even programming) classes. I’ve looked into it a little, and the bottom line is that no school district is ever going to pay me even half what my <Big Tech Firm> employer will pay me to shine their latest shiny app. I think it might make a good retirement career for me some day though.
