Sigh.. I for one will never understand why everyone is obsessed about titles.

Is doing front end not actual software development? What does that even mean?

Are you considered a real software engineer if you can write code in a certain language? .. Or does it mean you are really good at O(1) problems?

I think we should all agree that software development is a team effort, it requires vast knowledge and skills that different individuals bring to the table.

Doing CSS adds just as much value as writing the backend API.

Here is a good analogy. For an aircraft to function, pilots, aircraft mechanists, aerospace engineers all come together. Does that mean one is doing "plumbing"?

Certainly not, they all add value.
