I don’t give a shit about the title. I think it’s a joke. The analysis you’ve given suggests you don’t understand both software and engineering.

• Bandwidth is much more than what data centers put out. There’s a constant question of request/response size and the factors that go into scaling. If your idea of web development is just code minification, your idea is wrong.
• Engineers can’t pass the design buck. If you wouldn’t tell a hardware engineer, “the design of the circuit board doesn’t matter; don’t worry about size or crossed circuits,” then you can’t tell an engineer the use of the systems they design is just the realm of the designer. I know a few industrial engineers that would be annoyed by your ignorance of an entire branch of engineering.
• Why does everyone want to be an engineer? I’m really missing that point.
