Buddy, if you think that is "real engineering", you've got a lot of things to learn.

Even in software engineering, rails and react aren't really engineering. Real engineering includes calculations -- data structures, algorithms, data structures, and user interfaces designed to work with people who are deaf or blind. You wanna tell me that rails is performant? Have you done calculations? You wanna tell me react's algorithms are well-defined in memory and time? Have you ensured that your "software" is usable by people with disabilities?
