It's because we still have no standards as a profession. Whatever bullshit trends in silicon valley, suddenly everyone follows it, petrified that they might get left behind or are missing some important new thing.

I remember when Systems Administrator was a noble and important profession full of smart, talented people. But a lot of people misunderstood it and made fun of it, so it became an unattractive title, and instead of changing the role, they just made up new titles. Now they're cool and in-demand, and still nobody understands what they do.
