Does everyone go into software development with computer science degree?

A CS degree isn’t essential to getting a programming job. The US has over a million programming jobs, while there are only about 20,000 new CS grads each year. It’s impossible for CS programs to meet the demand. A STEM degree (excepting biology) along with three or four programming classes is all that’s really needed to break into the field. Most of the programmers I’ve worked with have not had CS degrees.
