The exams and credentials part is certainly murky. One could argue we make it worse in tech. Among the certifications I hold is at least one with "certified engineer" in the title (RHCE), but that's hardly only ambiguous one, with "engineer" showing up in all sorts of vendor and third-party certs and "architect" and "auditor" also finding their way into many others.

Are those phrases misleading? I don't know. I certainly feel like I worked pretty hard to earn and maintain the certifications I hold, but I can't compare the rigour and level of effort to licensure, because that's not required of me for what I do.

I also know that there are quite a few "certifications" out there that aren't rigorous at all, that are basically multiple-choice exams you can cram for without actually learning anything. I've never bothered going after a CompTIA certification for that reason.

It's a tough problem. On one hand, I despise artificial barriers to entry on principle. On the other hand, being able to understand and trust a person's base level of understanding and competence does have value.
