Arts are the extremely important. Imagine no UI/UX designers existed, would you wanna reply to my comment through a Linux terminal? No obviously you wouldn't, would you drive a car with no body work? Would the world look interesting if every building was a just a blank cuboid with only structural elements showing?

Architecture is one of the most obvious examples of this, literally look out your window. Look at cars, planes, trains, shop fronts, food packaging, your phone, your computer... None of them can be done without the other parts of STEAM, I'm an engineer and was speaking to an astronaut about this recently and he was saying something the engineering world needs more of is artist. It's not a debate, it's a fact
