Seems like the biggest barriers to learning cool shit is the prerequisite math. If you take a math BA, then you can most likely pickup whatever you actually want to study very easily in grad school (physics, cs, engineering etc).

Given that I like math, is there any reason for not doing this? If I look at my university's cs ba, ca ma and math ba, all the interesting cs stuff is masters-level, and the ba meme is just forcing you to do tons of boring shit
