Why are people surprised? Taking all the coursework in Math, Programming, Algorithms, Operating Systems, Computer Networks, Security and Cryptography, Distributed Systems, Databases, etc., and also learning and internalizing all that knowledge is a significant time investment. Yet many people here would be offended at the idea that you can't be a proper engineer without a CS degree, and would insist that all you need is a three-month JS/Angular bootcamp and then you're golden. A formal CS degree in itself may not be a requirement, but the time investment in acquiring the knowledge sure is.
