The dirty secret of software is scalability. Scalability to big O, big O to algorithms, algorithms to computer science. How do you like me now.

You don't want to use the right software language or framework with the wrong approach. You want to be able to reason clearly about the core problem and understand the tradeoffs of different classic solutions. Or invent a brand new approach. Or invent a framework or invent a language if necessary.

Consider this a plug for at least undergrad level education in CS. You can learn most of the rest of it on the job, but not computational thinking.
