Back when I started, I think maybe half of the people I worked with had a relevant degree at most. Even that might be an overestimate.

Back then, CS degree programs didn't even teach higher level languages than C/++ as they were thought to change too quickly. Whatever you learned during your four years wouldn't apply after you graduated. Instead, the programs focused on the low level implementation details with the theory that was where the engineering and science were.

Now, the same school I went to has courses and tracks for web technologies, so who knows.
