I don't agree with the parent about journalists (or that software developers should be licensed in general). But I would point out that, especially for engineers involved in signing off on certain things from a regulatory perspective, there is a Professional Engineer license that's required for certain jobs. I took and passed an Engineer-in-Training exam at one point because had I continued in my then job path I'd have wanted to become a PE once I'd the requisite amount of time.

We don't always need to apply an idea in the abstract to everything in the world. There is a big difference between someone who makes CRUD apps for a living, and someone who writes firmware for a pacemaker. No need to paint with such broad strokes.

Add to that , journalists may get fired but dont go to jail for spreading lies.

There is a law on the books for that, though I don't know of any journalists who have been prosecuted:

Such rules already exist and are widely ignored.

We do in Canada.
